The best way to do it is definately 41236 A+BB 41236B. By doing the 41236 fast and precise enough, you'll get every time a iFotd (a faster grab without the glowing staff animation) It's the same command as the asura's last hit ;)
I really don't think it would work because to imput the grab you have to do 236+ if you do 236+ instead it will start Heaven Monument (unblockable). I didn't know you could cancel the animation of the start. Why bother making 41236 when 236 is enough ? And when do you do 46 ?
