I think opinion will vary on this, and if you look at the thread for the vertical blue comp. what can be done on frc is changing by the day, with that said all the world records , still done with packing. Don't know your experience level or pb so don't how far your pushing your statics or your breath-up,how often you do static, relaxation is certainly a key factor and initually this could be easier with a bit less air- but keep in mind you can increase this confort level with more air by lots of thoratic stretching(pack stretching helps) but might want to take a course to get into that stuff, flexibility can also help managing contractions.---I,m at an intermediate level right now, my PB right now is 4:30 contractions start as I neer 3:00, I got to 4:00 for the first time in a course and seeing the video my contractions were super violent the last minute, after a better stretching regiment I manage them allot better, for the moment I'm attributing that to better flexibility--this is with full breath-up full final breath. anyway thats just a few thaughts I'm sure others could give you a more specific advice.---take a course if you have not taken one, they work wonders almost instantly and expose flaws early before you cement them into bad habits
