Nap QuikSpin ST Vanes. The toughest vanes on the market, QuikSpin ST Vanes let you spend more time shooting and less time re-fletching. With its lower profile, the new and improved QuikSpin STÆs now shoot even more accurately, especially at longer yardages. Patented micro grooves on one side of each vane channel air over vane for flatter trajectory compared to conventional vanes. The patented ôkickerö increases arrow spin by as much as 300% compared to conventional vanes for tighter groups even with broadheads. The unique combination of our patented kicker and micro grooves stabilizes and arrow in less than half the distance of a conventional vane or feather.
