Well that is impressive.
How does it effect your speed and flexibility though? I would guess that it would be far easier for you to pull something than someone of a comparable build to say, Jet Li.
I'm sure you and "the iron bull" are fast enough to make, what, 6th dan? But in practical application, like for sparring and stuff, do you find it difficult to spar smaller guys because they might be quicker?
I've noticed that when I started lifting heavier weights, I was markedly slower on the heavy bag, and while I was stronger, my power actually seemed to dip. I would imagine that to be because punch speed actually generates as much or more power than actual strength - but you can't really have 1 without the other.
