I've shot a whole bunch of different broadheads in 39 years. I haven't hunted with a mechanical so I can't help you. My past 15 years or so were all done with Thunderheads with experimentation with a bunch of others I never took hunting. I killed my first deer with the Shuttle T by Tight Point last year. Len has been using them for 3 or 4 years. I really like they we they fly. Better than all the ones that claim to be the best and they seem to tear a whicked hole in a critter. All have been pass throughs out to 40 yards. So, I'm a Shuttle T guy for at least next year. Hard to find up here, I have to order from Len.

Big deer, pass through of the shoulder and out the other side.[8D] ya got to love it.
