RE: choosing a broadhead
some very good heads to consider are the Steelforce, Phantoms, Bear Razorhead, Rocky Mountain T-100, Rocky Mountain Ironhead, Muzzy 100/125, Thunderhead 100/125, and GKF Deadhead 100.
Th emain thing is picking a head that matches the game intented & to consider the amount of energy your rig produces. all the heads I mentioned will work fine on elk. just look at several models before you buy, that way you will get a good head that you feel confident with.
Happy Holidays
