I love them. I was a bit concerned when Trophy Ridge bought em out, but they only made them better. The older heads had a really short thread shank which only screwed into the inset a couple of turns. Now, they are longer and much more secure.
I shot a doe on tuesday, and the exit wound was an 1 1/2" and took the hide and fur right off! I think you'll like them. There is no noticable flight change out to 40 yards. I don't shoot much at 50 so I can't help you there.
At 11 bucks for 3 thats a good deal. I found a guy on ebay who had them at 2 pks for $25 which I thought was good.
Anyway, get 'em. They're nice broadheads.
