Box shape frame on P,for offensive play,and Aero shape frame on T,for maneuverability. Note that T usually has heavier head than P.Armortec lovers won't expect getting a head light feel from an Armortec series,hence due to the aero head shape,Yonex designed it to be head heavier,so that it won't lose its head heavy feeling during every 900T's faster swing,compared to the P. 900Power and LCW,their shaft stiffness and head heaviness were different.LCW's more stiff and head heavier..
