Mechs. on Elk
I agree with Mez. Stay away from mechanicals on elk and for that matter big bodied deer. If you want to shoot a fast setup like yours with light arrows, look into a good compact broadhead that's easily tunable. It's all about shot placement and woodsmanship. FYI, most ethical guides I know will not allow or discourage hunters to shoot elk or big bodied deer with mechs. Good luck.
