So, I got a heck of a deal on a Zav bent shaft paddle, but I think it is too long for me. The guy I got it from is the same size as me, but he only used it once (according to his pitch) on a trip ten years ago that he was talked into by a friend. He did the trip and decided canoeing was not his thing, then put the paddle away and forgot about it for ten years (wealthy people do odd things). Anyway - I don't think I can rely on his judgement for paddle length. It's 52". I'm 5'-11" and usually use a 52" or 54" straight. Shouldn't I be shortening this to 50" or less?
