I have a SA2 170 and have off-heading openings and end-cell closures on every jump-sometimes the openings are so off that it throws me into line twists. I have been researching SA2 170 opening's for a few weeks now because I was convinced it was my pack job that was causing it-obviously not :-(
My wing-loading is 0.9 and this is my 1st canopy. I bought it when I had 27jumps and have put 50jumps on it. I am very much a baby jumper but have been packing for myself since I was licensed which is what led me to think it was me. I had my reserve repacked along with my main by my home DZ's rigger and the heading was still off and I had end-cell closures.
I am beginning to think it's the canopy & I may need to consider a new one.....
