Alright...I'm thinking about starting to build my own arrows....they will be using carbon shafts....but alright...i hear about straight, offset, and helical..i mean they are pretty self explanatory, what the heck is an arrow wrap....and is there some kind of good write up or instructions somewhere how to do it?...I'm just getting into this and I'm a newb at it...but if someone could write up good, detailed instructions, and an inventory of what i would need it would be greatly appreciated...thanks!
