Custom look but bright colored wraps make arrows easier to find when you miss or see your hits on game. One advantage I've found is it makes refletching easier - peel off the wrap and old fletching comes with it (less clean-up on shafts).
Don't a need a "custom look", but being able to refletch wiithout scraping off flethings would be a plus I'm shooting Beman Centershot shafts that have a fake wood-look finish, which is easy to scrape off when removing feathers. The wrap may be an answer.
Thanks!
