At first moment, i was considering the openings PERFECT, I did 5 jumps just for test the flight of canopy, pulling at 8000ft, so didn't really matter how much altitude i loose. But on the next jumps, pulling at 3000ft, I noticed that the canopy was open and totally inflated (after help it with rear risers..) at +-1800ft or less..
I do pro pack and don't roll the nose.
In fact, the slider comes down really really slow, if it doesn't stay on the middle of the way..
I have to tell you that I liked the openings, really.
Extremely predictable, soft, but a little bit slow.
Better don't pull low...
