I have not tried these braodheads or seen them tested but some of my mates have tried some similar and didn' t like them at all. My mates and I use a two blade blackstump broadhead with great penetration, strength and damage to the quarry. Does anyone know how much the crimson talon 100' s cost cause they look pretty damn expensive, I' d be guessing around AUS$20 each. The Blackstumps are very popular in Australia and only cost AUS$4 each. Although the Crimson Talon 100 might be a great broadhead I find that the two blade broadheads do the job with ease.
