I prefer Dacron lines, but they do cause the canopy to fit as one size larger.
Also, I use the standard rubber bands (NOT the shorter ones for microline), and double stow. Usually loose around one per jump on average (I also take them off if they are showing that they will break in the next few jumps). Remember, you need them to:
- Hold when they should (good condition, right size band, right size bite, and tight enough - double wrap helps this)
- Release when they should (right size band, neat bits and stows)
- Break when needed (rubber bands or tube stows*. NOT castration bands, O-rings, or other solutions to "save you money and time") Its the difference between changing a rubber band and having a high-speed malfunction/reserve repack/finding that lost main that's still in the bag... yea... good luck with _that_ needle in a hay-field.
*I like tube stows, but I know many folks don't... not trying to start _that_ flame war here...
Having said that, TALK TO YOUR RIGGER.
(s)he should be able to show, instruct, teach, demonstrate, and double check your work on this... if they won't or can't, TALK TO A DIFFERENT RIGGER...
