This point will go through the eyes many times during a day, and should be as slim and smooth as possible. I personally prefer the spliced eyes on both ends of the shooting head, which enables me to change both leader and the whole head without tying knots. Others prefer even smoother splices like sown or glued ones covered with Aqua Seal or a similar compound and a good old fashioned nail knot, which indeed transfers power beautifully to the leader and the fly. Many fishers prefer cutting off a part of the front taper in order to get a stiffer front part, which will better turn over on power casts and better penetrate the wind. Look at the taper.
Many fly lines have a tapered section and then a long, thin tip.
This tip doesn't do much work in the cast, and might as well be removed. A radical piece of advice regarding the taper is to totally reverse the shooting head as mentioned above. This will leave you with a head with no front taper, which does not give the most beautiful casts, but will enable the line to cut through even rough winds. If you have attached the head with loops it is worth the bit of trouble to try this configuration. This link will bring you there .
