I see your thread got lost in the mix!!

Yes cut on contact start to cut the hide as soon as it hits it.

A chizel type head will "punch" through the hide until the blades start to cut.

I have killed deer with both types. Muzzy is a fine head, but I have been using Montecs the last 4 years and I love them. Be warned if you go with Montecs you will need to spend at least and hour on each head to get them really sharp.

I tested the G5 Striker and loved it. Cut on contact and just plain scary sharp!!!!! out of the box. Next season I will be using G5 Strikers. One thing nice about G5 is all their broadheads are spin tested. They all fly the same!
