The Talons use up a lot of energy in the animal because of the "aero-foil" fins, thus reducing penetration. I would stay with COC. Typically, the more blades and surface area on them, the greater the reduction in penetration, so keep that in mind when deciding on two blades, three blades, and bleeders. Some quality ones are: Magnus, Muzzy Phantoms, Simmons Sharks, Wasp Sharpshooter, NAP Razorback, Razorcaps, Steel Force (non-serrated), Sonic/American Broadhead Company, G5 Montec and B-52, Zwickey, Bear. Probably the only chisel tip type head, like the Muzzy, I would consider would be the Innerloc. Innerloc actually makes a two blade version and the chisel tip is smaller than the Muzzy, though very tough. The Muzzy would probably do the job, but the Innerloc in that configuration would penetrate better.
Smaller profile heads like the Wac'em, G5 Striker, and the Sonic/Americans offer a lot of penetration in the popular 3 blade configuration however.
