Actually the same thing was happening before, that's why I decided to refletch. The vanes were starting to look really worn, 2 or 3 times as bad as in the picture.Perhaps I should refletch again and switch from helical to a straight fletch and try that? I mean this really isn't THAT big of a deal, it isn't affecting my shots any, but I'd really like to fix the problem so I don't have to refletch as often.

Yes I've tried shooting cock vane up, but the cock vane STILL for some reason makes contact in the same spot.
