I just ordered the NAP Quicktune 360 from my local archery pro shop, hopefully this one will have the new concave part instead of the teflon. I use the Whisker Biscuit right now and since i shoot quite a bit and notice the whisker biscuit damages my vanes after a couple dozen shots (it isnt affecting accuracy but i dont like the fact that some vanes are beginning to peel at the tip).

I am going to order the new "Quicktune Post Cap Upgrade" @ 1-800-323-1279
