Yep. ;) I like SU-Sensei's too, but I couldn't even begin to reproduce it in print.

I always thought the thing about scaring the opponent (as opposed to focusing your own energy) was a bit silly, but R--'s kiai makes me flinch every time. I swear it's damaging my hearing. However, it's better to have your opponents more scared of your techniques than of your kiai than vice versa.
