Home Forums Hunting & Shooting Bowhunting Broadheads for elk ?

I'm thinking, if all goes well with my back surgery, I'll be ready to do some big game hunting next season, and thought I'd put in for archery elk.
Besides replaceable bladed heads like Thunderheads, I'm looking at these 3 types.
60 pounds should put any one of these, deep inside an elks chest.
Now, to choose which type ?
All are 100 grain.
