bailer3,
Don't over look this factor. I have arrows that when I added wraps, they were way too stiff. I used paint, and they came back into line. Naturally it is not a factor until you get to the borderline area. This is why bareshafting is so important, put a heavy wrap on and get it close, then fletch them and have them hit the spot. I love the ease of wraps, but they are really heavy when compared to dips, or paints(if you thin them correctly), when I buy wraps I go to "Onestringer".
They have even made some traditional 11 1/2 wraps for me, good people, quality product.
