i'm a new skydiver, i've got 41 jumps, i look to buy a rig. My question is: what's the main diffrence bettewen a 9 cell and a 7 cell, and how is it fly under a spectre 170. I'm used to a saber 2 190, is there a big difference bettewen a 190 and 170.
Sorry for ortograph mistake i'm from montréal.....
