I prefer muzzy or other such heads better than mechanical heads. If you spend the time getting the muzzy's tuned they'll fly consistant for you. I believe a lot of people shoot mechanicals(not everyoneplease don't flame me) to aleviate tuning issues as opposed to fixing the problem. Both have their place in hunting but I prefer to let Mr. Murphy bother others when I'm hunting. With mechanicals there is one more thing that can go wrong.
