Recently I deployed my base system and encountered a problem: It just released one side.
I heared about that several times and deployed the system several times on the ground, but I never thought that this is possible. The middle ring stuck in the carabiner so strong that I hung on that one side and had to push the ring through the carabiner manually.
Probably I have to add that I pulled the release while flying straight ahead and being tandem passenger, so there was no force to pull me "away" from my suspension point.
I am using the AVA Base 2015, having the round carabiner as "biggest ring".
I compared my carabiner against the one from a friend's and was discovered that is's smaller than mine, having a smoother rounding, the other way around mine is more elongated and oval.
But my actual question is that I am searching for a new carabiner with a huger diameter and probably made from a bit thinner material. Mine has about 32mm at it's widest point and 9mm thikness.
