I shoot the Grim Reaper razor tips. They haven't failed me yet, fly just like a field point, every deer iveshot hasn't gottenmore than 60 - 70 yards. You should go to their web site and watch the videos of their tests. They out penetrate and more durable than any broadhead they tested. and they tested muzzy, thunderhead all the major brands except maybe the Rage don't think it had hit the market yet. They shot the razor tip through a 50 gal. steel drum, it penetrated the front and started to go through the back, and didn't hurt it a bit, still fully functional.... its unbelievable.
