I bought a few packs of the NAP XB Quick Fletch vanes for my Center Punch Evo X arrows as spares in case I happen to tear off some vanes while practicing. My concern is how well will they work if I have to use them. They are 1/2" shorter than the factory vanes and appear to have some what of a helical twist as opposed to just an offset. Granted I wanted to buy a fletching jig, but it's a bit confusing and tough to find the right jig for arrows with a 2% offset. I long for the old vert bow days of a simple Bitzenberger jig and then buying whatever Bitz helical clamp you desired for it. Anyone tried these NAP XB QF's? What jig do you use/recommend for your arrows that gives you a 2% offset? Thanks in advance for enlightening me!
