Arrowbuster, I actually tune my arrows with broadheads, because I can really see what's going on. If you are RH, it's definitely too weak. I figure you'll need a 55/60 or 65 # spine shaft, depending on length and broadhead. Heavier head, go 65# and start with a long shaft, cutting it shorter. Hill style will tune in nicely when you get there. Also, you shouldn't need a really high nock. Try nocking over a nock point, I can shoot a little wider spine range by nocking over and it reduces some of the downward torque on the arrow.
