Renting is fine, if you use the oxy/acetylene torch frequently, or
can manage by renting the tanks when you need to use them.

If, as in my case, I use the torch two or three times a year and
never know when I will need it - renting is totally out of the
picture. It doesn't take more than a couple of years before the
demurrage equals the cost of the tanks.  When I need a refill,
I simply take the tanks to the supplier - they give me new tanks,
so I don't have to worry about old used ones.

Rob Tyler has shown a video with a low pull at West Tennessee Skydiving.
It is made from the ground. The side of the hangar is in the picture, so
it's easier to judge the height. From an RW load, a guy just keeps
falling. You can see his face. Finally he pulls, and gets line stretch
at about 200' . To say that he is crazy is a big understatement.
Just a little one-second problem with deploying or opening could have
messed up his whole day.

It's amazing how much difference a 3" hole in the slider will make in 
opening rate. It's easy to make your canopy open FASTER (just ask any
base jumper :^),  but slowing it down can be a real hassle.

Nice way to tie the steering knot, but also can take a small piece of
clear plastic tubing and fit it over the knot in the steering toggle so
that there would be no chance of it ever going back up through the metal
loop and getting caught. You can also do this for the risers so that
when the slider comes down it doesn't bang on the metal connector links
and start screwing up the brass slider rings . All these are tacked down
with mack tack to keep them in place. As far as velcro goes, it is
imperative that when you land, that you put your steering
toggles back on the risers to prevent that fraying that you were
talking about. There are better means to secure the top flaps than
velcro now also. Ask your rigger if he can put tuck ins instead. He
will know what they are. They have small tabs that tuck under when the
flaps are closed. They are put together with a bit of stiffening
material so that velcro does not have to be used at all now except
maybe for the steering toggles. I have over 600 jumps on this rig now
and no fraying at all on my risers. BOB!!!

           I'm *not* able to walk without a significant limp right now,
and my ankle strength isnt't great. Anyone not involved in the sport
(doctors, therapists, friends, etc) will (of course) advise me to
wait before jumping again. However, these same folks would really
recommend that I *never* jump again.

   I know what you're going through guy. I've been off for about 6
months now and think I'm ready to go back. I was planning to start back
and borrow a bigger canopy like a Manta for the first while about a
month ago. But every time the ankle felt like it was back to normal the
muscles started acting up again.
   I'm really glad now that I waited, the ankle feels pretty much normal
again and I think I'm going to use my own rig when I go back,

Panasonic makes some VCR's that can play back a NTSC tape on a PAL TV but
not convert to PAL.
(well some PAL TV's, not all because they are cheating)

And there is a multi standard VCR also from Panasonic which can play
and convert all standards (PAL,NTSC,SECAM) but it costs 3 times as much

Why worry about the reserve being too big. When you get to the point
that this is the chute you are using then the fun part of the jump is
over and this is the parachute that saves your life. If you are happy
with the container (Elite) then having a smaller reserve  is just for
looks more than anything. Nothing wrong with a bigger reserve as you may
be in a place sometime that is quite high and you will be happy that you
had the bigger chute. You are right about the main but I think that your
instructor was thinking of your safety right now not about how fast you
can fly a new main. Get some good practice with the new bigger main and
then start to experiment with something smaller. Jump a few differnt
ones to find out what you like. Jump the new mains in your own rig to
see how they fit and feel and then make your decision. Keep away
from borrowed gear that you are not familiar with as this is
inviting problems and the mains may fit nicely in the rig you are
jumping but may not be as nice in your own. The bigger one will give you
better landings with more margin for error. Fifty jumps is not that many
and it only takes one small mistake to break a few bones or worse. You
will be able to sell the main to someone who is a beginner next season
and get your jet if you wish then. Smaller chutes come down much faster
than bigger ones and they look great as long as you are under full
control. Boy they can sure hurt if you make a small correction too close
to the ground and your flare is a little late or a little off. The Racer
will take a smaller canopy and your rigger can make adjustments for the
smaller main. Most guys up her including myself have bigger reserves
than mains just for the reasons mentioned above. BOB!!

I don't have my SIM handy, but I seem to remember that you're allowed one
deliberate familiarization jump on your reserve.  (That is, used as a
main.)  Any more jumps on it as a main, and it is no longer approved for
use as a reserve.  Besides, I thought that one of the great comforts of
reserves is that you know they're in great mechanical shape with almost no
jumps on them, and that the fabric is "factory fresh".  I jump a Raven III
main, but I'll have no hesitation about going to my Raven II reserve if I
need it.  Heck, it'll probably put me down softer than my main!

The student radios we use at IVPC are made by Motorola.  They fit in the p

is plenty loud for it to be heard from the arm, since the arms are usually
up near the head to reach the stearing toggles.  Work fine for us.

If it opens in time. All other things the same, the larger the parachute
the slower the opening. An amazing number of people find this out the hard
way by buying a main that's larger than they need. It's a recipe for snivels.

I think major DZs where there are lots of European visitors facilitate
video system for doing that.  I remember Deland ad mentioning that.

Also you see adds in video magazines for dubbing services.  Among them,
you should be able to find company to do PAL conversoin.  You might
have more luck asking on rec.video.

Also, since you are in Colorado, why don't you try SkyHi Visual?  I
remember their order form had check box for PAL format so they should
have equipment to do that.

Glad you are on the mend. Those ht's will do it every time. Spent my 10
days in hospital about 4 years ago so know how you feel. Why worry about
size. Get something you're comfortable with and jump it till you feel

Some performance statistics please....!

I am soon to be purchasing my first rig. Would like
new, but some used equipment has been looking pretty 
good also. One option I have is a used rig with new 
main. Needless to say, the main is the issue.

My weight is 160-165 and have made several jumps with a
200 Raider (?) 7 cell main. Have 20 total freefalls and
am fairly aggressive in all other sports.

Have been considering the PD. 190, but was told this past 
weekend from a DZ owner that for my size the PD. 170 would 
be a better canopy. Is a 1:1 ratio a practical idea? His 
input was that the PD seems to fly a little better when loaded
a little heavier. Any feedback? I would prefer to buy up and 
not just into, my ability. Dont want to be bored with the rig
after just a few dozen jumps.

Would a Sabre 190 be comperable to a PD. 170...? Sabre not a 
good consideration for a new jumper?

Thanks in advance,
Jim

9 cells also have a higher aspect ratio.  The aspect ratio is the length
measured from end cell to end cell (called the span) divided by the length
measured from nose to tail (called the chord)  Higher aspect ratio canopies
have different collapsing characteristics.  For example they're much easier to
horseshoe than canopies with a lower aspect ratio.

This is true.  But it makes for a dangerous CRW combination.  Use your
imagination:  a fast flying canopy that doesn't take much effort to get the
ends to flail around.  Now put a persons body in front of it.  The potential
for a wrap is dramatically increased.

If you're interested in CRW, you have to consider carefully whether or not you
want to get a 9 cell.  I know people who do CRW with 9 cells.  I also know
some serious CRW enthusiasts who will not do CRW unless there are only 7 cells
in the formation.  Their theory of operation is that CRW is difficult and
dangerous enough by itself.  There's no need to add a (relatively) unstable
canopy to the complexity.

The guy that took 2nd last year came into the competition with only 17 
skydives, but with 145 hours of tunnel time. He noted that skydiving is 
easier than tunnel flying because in the tunnel you have only 11 feet
to work with, and so you have to be more disciplined. He slid all over 
the sky, which I found to be rather amusing. And didn't he hurt himself
landing this year?
