As mentioned, don't buy into the favorite b-head BS..... hit a deer through the lungs and it's DEAD and DOWN within 100 yards!
Also, please don't use a mech b-head and excuse or crutch for using a poorly tuned bow.
That being said, the highest quaily, best penetrating b-heads I've found are the Rocket Steelhead, Wac 'Em and Slick Tricks.
