RE: Best Mech. Head.
Frank (Kidd642) nailed it: Go with what you want, but you'll definitely do yourself a disservice if you don't look into the Rocket Aerohead Miniblaster!! It'll open up in ANYTHING (I 'bout split a turkey neck into a few years ago), and has a 1-3/4" cutting diameter. It's truly an awesome head.
