I would seriously recommend you to take a look at Slick Trick Magnums (in either 100gr or 125gr depending what your intended FOC is) and G5 Strikers. They are both very sharp and blow through animals like you wouldn't believe it, with moderately good KE. These broadheads spin great out of the bow and will hit with your field points with good tuning (paper, bareshaft, walkback, broadhead).
Muzzy's are hell to tune because of a lack of consistency in spin test. The ferrule on slick tricks and strikers is steel, not aluminum like muzzy.
