I am shooting Easton Axis arrows. I am going to go with the G5 Montecs this year. Can any body tell me if i need to use broadhead adapters with this setup. If so, is it better to use the easton ones, or will the NAP universal adapters work?

I use the Steelforce Sabertooth heads on my Axis. I have adaptors on mine. I think mine are the Easton adaptors.

I would imagine that either one would work fine. Just verify at your local shop or email Easton or NAP.
