RE: Is my new set up sufficient for Elk?
Ditto on Zelazny's post. A 60 lb. bow with a rating over 300 ibo is plenty for elk (even at 28"). Get your total arrow weight to at least 425 grains and you will be fine. Another suggestion is that a good cut to the tip head like the Magnus Stinger will most likely gain you some penetration over your Muzzy's (Muzzy's aren't a bad choice, though).
