Thanks for replies.
Ignore the bit about the 5th line snapping that was times when I was unhooked in flag out but the 5th was wrapped a few times so took all the strain.
I can c why u'd want to be floated back to the water after missing bar. I'm not advanced though and not getting much air so for the mo that isn't a priority I'd rather just not get a hard drag through the water upside down after crashing. I know I do tend to hold onto the bar with one hand too long when bailing out of a trick (in panic) I guess I'm asking for trouble on any setup doing that
