I have been looking into buying some new broadheads and wanted some opinions on the best COC heads. I am looking for toughness and blade sharpness. I have recently been looking into the Magnus Stinger 4 blade, and the Hellfire Premium Titanium and Premium 4 blade, both from Steel Force. I was wondering about the titanium being brittle, and the edge that comes on all three.

Anyone had any good, bad, or otherwise experiences with any of those?
