Just to be clear, I have never found my Go-Sports to be lacking and I have been in a lot of current. And some of my dive buddies are pretty good divers. And nobody is passing me up despite my camera. The only place they seem too flexible is when I am sitting still, we all see a turtle or shark or ray and I hammer them to get moving so as to get there first, lol. They buckle a little too much in the mid section just for that instant at a standing start but soon catch up and give me all the Go I have needed. To be fair, I have that same issue with Quattros, the buckling right at the end of the toe pocket.
