Another great broadhead are glue on 11/32" STOS broadheads. A 2 blade broadhead that is easy to sharpen, very strong, the tips don't curl and they fly great in flight. They come in 130, 145 and 160 grain weights.

You would have to glue a 11/32" screw on adapter to them.

I get my 2 blade STOS broadheads from Braveheart Archery.

BTW, you don't have to use 2 blade broadheads. You can use 3 and 4 blade broadheads as well. Right now, I'm using a 3 blade broadhead for both of my recurve bows since I've switched arrows this year.
