I shoot/hunt a lot of elk. I use a mathews feather max. 2216 aluminams, thunderhead 125's, You want a heavey arrow and fixed blade broadhead. also I use a low profile mathews quiver and I hunt really thick stuff here in oregon , Idaho is much more open. The best piece of advice I can give you is practics shots up hill and down hill out to 40 yards, FYI I don't like carbon arrows for elk hunting. IMO they just don't have the weight, also don't try and hit the heart, shoot the lungs . Heart shot have a tendance to move to close and hit that massive shoulder blade.
