Okay I've read all of 5 Shots reviews and have narrowed my choice of mechanical broadheads down to the following. These will be 100 grain. I'm also looking for a larger cut diameter.

Spitfire Snyper Wasp Hypershock Gator

My arrow specs are:
Arrow Weight

KE

I will be hunting deer (98%) and black bear (2%).
