I almost forgot... I use 100 gr. Montecs. Recently we had a customer bring in an old beater bow that he longer wanted... so with nothing better to do, we did an experiment. We took an assorted group of broadheads and shot them into the limbs, & riser of the bow. I wont mention which BH didnt do squat but i will tell you that the Montecs and the SteelForce 2 blades did exceptionally well. Both had great cut on contact and completely seperated a single-limb down to the limb pockets, and nearly penetrated all the way through the riser! Just imagine what it would do to a shoulder blade
