Ive had 2 cutaways in 42 jumps. I succeded in getting the first one in my first jump. After analizing the situation I think I overreacted to having a couple of endcells which werent inflated. I actually tried to pump a couple of times as I was tought, but as nothing happened I pulled the reserve. The second cutaway came at jump 33 and was a lineover with a spinning canopy. I reacted promptly and actually felt pretty much at ease with the situation. Both were with studentgear, navigator and manta. Thanks to this I at least now know that im capable of saving my own neck in a situation like this. I still do feel nervous going in to the plain and gaining altitude. This usually goes away with the freefall though.
