? for Nock on. Can you give more specific info on your setup? I have always found the Nitros to be a bit difficult to get bare shaft tuned. When they are right, broadhead flight is no problem at all, but they have been tough to get tuned just right for me. I will probably be getting a new dozen arrows soon, and was going to try something else. Maybe I will get some more Nitros. BTW, I have used both Nitro Greens, and Nitro Traditionals. The Trads really quiet the bow nicely, but do tend to drop off quickly between 30 and 40 yards. Thanks
