I have never used them, but I think my hunting arrows will be sporting them this year thanks to PAHardwoods. He makes some awesome wraps and can pretty much design whatever you want, which is nice because you won't have what everyone else does at the range. Enter the "coolness factor"

I run into a dilemma last year on a deer I shot that I didn't have a clue as to exactly where he was hit. Had I had my arrows wrapped might have made a huge difference in tracking the arrow during the shot.

Weight? They add a little, but like PAHardwoods already stated, they wont add enough to talk about really.
