Wheh! I feared you were talking deer or even elk ... for which Sharks are already lame (Ashby) and bleeders would make them moreso. For turkey's however, we want heads so big they'll slice 'em in half for us (so they don't run off and hide, unrecovered, which I'm convinced happens far more often than we wish to admit). Good idea! I use the giant old 3-blade Bodkins and MA3 heads, plus lighter bows and penetration limiters -- among the worst ever heads for penetration in big game, but which knock the poop out of turkeys and put 'em down quick, for sure recovery.
