If you're getting fletching contact, then your rest probably needs the timing adjusted, or your nocks aren't rotated properly. Lot of guys enjoy good results with Blazers on that rest and the QAD.
Thats exactly it.
Blazers aren't the issue here. If you are getting contact with blazers, then you'd probably get contact with just about anything else too.
I know a few guys who shoot long range target comps (FITA and the like). Most of them are either using mini-blazers (1.5" models) or some other type of short vane. I target practice, with broadheads mind you, out to 80 yards with NAP twisters, and I've done the same with 2" blazers and feathers both. I put a soft right helical on mine and they work great.
