I've tried them before anyone even heard about them. They were designed for compounds. When you draw a compound back to your anchor and release the nocks will open up after the cam rolls over and really slams down on the nock. A trad bow doesn't have that rollover and as the string is released it's just more of a consistant flow causing these guys to act like little vise grips on your serving, then trying to jump off at the last second causing eractic arrow flight. The little pins inside the nock really do not open up without the initial bump of a cam. These little buggars had my arrows going crazy! Get yourself some Easton 3D super nocks if you want great releasing nocks. The accunocks do work great on compounds. This is just one shooters opinion and we all know what that's like. Don't want to get slammed here, just giving my honest review of them. I gave the ones I had to a friend of mine, now he really dislikes me, LOL! ~Rich~
