I read about the carbon gear also but I think the reason most wanted them was to avoid the bending of the aluminum gear and having to straighten them after hard landings. I would also assume that most people think the carbon gear would be lighter too. I'll try and to keep all my landings on the greasy side....lol and if I do bend them it's for sure I'll straighten them out many times before I spend 70 bucks for carbon gear....NO WAY
