1000 camera jumps a year and 200 jumps ago I donned the Mirage. I love the idea of hard housings in the risers. I have chosen a M1 size container with a PD143 resereve, which is the max size for the rig. Because of this I have a relatively small rig, but the compromise comes in the form of a firm packed reserve that perhaps doesn't mold to you as well as a smaller reserve or larger container might. This is not a ctizisim of the rig, just an observation of reserve size v container.
Lessons learnt - Follow the rigs packing manual closely.
I beleive this is very important and also helps make sure that unstowed line is not caught around any stows. You can monitor the free-line easier if you put the bag in this way. Plus, Mirage are right it fills the bottom of the container better. It gives the freedom to do any type of flying I choose without having to worry about anything coming undone. Mirage simply makes the best rig out there.
