RE: crimson talon xt (100 or 125 gr??)
The Crimson Talon heads really seem to eat up alot of Kinetic Energy because of the design. The blades on them seem to be pretty dull in comparison to other heads on the market. You stated that your bow is pretty slow, instead of going the Crimson Talon route, I would look into a good cut on contact head. Such as a Magnus Stinger. I think at slower speeds, and lower KE, you will get better preformance out of a good cut on contact broadhead.
