If you look at the bevel it's like a chisel, it will dive in from the angled side. Flat needs to be the direction the rotation is heading towards. If that makes sense.
Yep right hec right bev and viceversa. What single bevel are you shooting? I'm shooting Strickland Helix's in my recurve and I'm gonna shoot them out of my compound this year also. Devastating!
Before choosing a bevel direction you should test your arrows to see which direction they naturally want to rotate coming out of the bow. Mark the shaft and shoot them bareshaft from 4, 7, and 9 feet. Note which way they want to rotate. Then fletch them helical in that same direction, and buy broadheads with the same bevel direction. Now your arrows won't have to waste energy starting to spin one way at first, then reversing direction mid-flight when the fletching takes over.
