Muzzy 100 grn fixed blade broad head. It simply works... don't fall apart on contact and for more years than I care to admit to, they've brought home the back straps. Of coarse you have to back up any good broad head with an arrow that has enough weight to help punch a hole through the other side so I use Easton AC super slims (11.5 grns per in.) Great kenetic energy down range. Still there's no replacement for "one well placed arrow".
