i use goat tuff, blazers, a wrap, and a helical jig. wraps are said to stiffen your spine a little. (dont know how true that is) the biggest benefit i have got from wraps is the fletchings seem to stick to the wraps a little better. you also wont have to scuff up your shaft before putting the vanes on, that makes it easier to take fletchings off when you have to redo them too.
