If you're looking to scrap the resin gear that comes with the Focus, Lee at Piedmont sells an aluminum gear as replacement. At $30 it's a whole lot cheaper than carbon alternatives. Weighs a little less than the resin. I have one on mine, works great. (haven't smacked it yet so I can't tell how long it will hold). It is made out of 7000 series aluminum, so it should be pretty tough. FYI, Chuck
