Interesting...so middle finger in the wrist crease being a and pinkie being b?
To anyone: what are the pluses and minuses between these two? I understand if everything else (structure) is solid enough it's probably somewhat moot, but I'm curious about different folks interpretations. I've been taught version b, for the record, which seems like it would potentially affect more bend to the wrist due to the palm being centered more on the back of aite's hand...but that's just my guess. Coincidentally, we seem to also really enjoy the index-finger "button" with the other hand for kotegaeshi...at least, the last few times I practiced it that's how we were working the technique.
Just read ealier on...um...I guess what I meant to say was...er...any more
thoughts? Too much coffee; not enough...oh hey shiney!
