I dove last night with the repaired wing. It performed fine. No more leaks. The pin hole was from some type of abrasion. IT WAS NOTHING TO DO WITH THE MANUFACTURE OF THE WING!!!!!! I just got back from a long trip around the world and the wing probably was rubbing aganist something in my lugage. I did take the backplate and wing and place them in a seperate bag so that was not the cause. I don't understand what all of the noise is about between Halcyon on and Oxycheq owners. This probably could have happened to any wing, regardless of make.
