Ive hit the tatami frc iad tatami a few times. Granted I do not use the psh to frc..I do ksh. From what I can see it helps to do 2d into tatami. Puts them in air a little more. But the frc into the iad tatami is almost instant. At least from the times ive hit it. One of my draw backs I get though is the the 236H lol. If my info will help u..probably not..however like I said the frc into the iad appears to be almost instant..might help if u start to buffer the motion as ur doin the frc.
