Thanks for the reply, I plan to give them a try indoors on my 2014's, would you recommend the 3" or 4"? I shoot recurve.I use them on both x7s and FMJs. They work fine.
I don't have the dedicated jig; my bitz with left wing clamp works perfectly well.
I use 3" but that's only because they were easier to get at the time I tried them and they worked so I had no reason to change.
In all honesty I bought them because I thought that they looked cool and a bit different but in all fairness I can't say that they are any better or worse than the Bohning x-vanes that i used previously.
