I'm with CG on this one. I'm no rocket scientists, but your current setup is more than lethal enough for any elk on the planet. We've taken elk with draw wts. from 40lb-50lb-60lb-70lb bows with heads like thunderhead & muzzy. I would say that most bulls were taken with 100grn heads, my son who's 23 has taken 7 bulls and 1 cow all with 100grn heads. Hit them where they live and they won't go far. I personally like 125 heads but you can take elk with either. If you're comftorable with current setup stay with it you'll be glad you did. If this is your first elk hunt with a bow I'd be more concerned with the excitement level when a bull is coming in close than your setup, cause your setup is excellent. Also your KE is 70+ so ther's no problem there. GOOD LUCK ON YOUR HUNT. ELKNUT1
