Not sure, since I haven't tried the Quick Spins, but I did handle a few, and they seem soft for a vane to be used with the Biscuit. I agree with the other guys who suggested Blazers. I tried them this year just as an experiment. Now all my arrows (and my sons' arrows) have Blazers. They are pretty easy to fletch, hold up well (no visible wear through a B2 Biscuit and several hundred shots), and control broadheads very well out to 40 yards, better (for me) than straight offset, 4" vanes. They are also less expensive than the Quick Spins.
