The BH you mention are all good heads. The problem you' d have in a shoulder blade shot is there are no vitals behind it, it' s to high of a shot for a bow. So it wouldn' t matter what head was used, you' d probably be looking at a long trailing- tracking job. Now a hit between the top of front leg and under the shoulder blade is deadly. And all heads you mentioned would do well. A two blade cut on contact such as Magnus makes will penetrate the easiest, but with 70 kin. # you' ll have no problem with any head, provided you hit in the vitals.

If I would only have one chance at an elk hunt, I' d choose Muzzy, have also taken many elk with Thunderhead, but Muzzy seems to be the toughest blade We' ve used. elknut1
