me and a few buddies used these before for some 3d, but we're not into it enough be serious. But they shot well.
With the uni bushings, on a shaft like that, I use the Easton super nocks most of the time because they are easy to find in my local shops. I've had the super 3d nocks too ( I think that's what the are called),and I do alot of indoor dot shooting, and those nocks do well for me.
for skinny carbon 3d shafts, like the accs, or whatever elseaccepts a uni bushing, we'd use the easton G-nocks.
I forgot to add........stick with a 4" fletch for shaft like that. We did a lot of playing around this year with our indoor spot arrows, mostly 2514's and 2613's. We tried blazers, quikspins and mini blazers.....anything you could imagine. We ended up going back to 4" feathers with a mild helical.
