never used them
but if they fly true out of your set up, thats all that really matters, and well you putting it in the right spot
I think folks over think the broadhead game, media hype or???
all you need a is a sharp head, and put it in vitals
and dead deer happens!
any head in a poor shot placement isn't going to magically make it a good shot!
started off hunting with bear SS tips plain and simple, but sharp, were like 3 bucks a head, and killed me a ton of deer with them
now, at 10-20 bucks a head??
getting silly if you ask me!
but good luck, and post follow up on how you like them after a kill or 5, LOL
maybe others will follow you and try them pending your results??
