i would like to be able to recount his reasoning but i know i didn't follow it then and can't possibly do any justice to it here, mostly because my knowledge is limited and i have a lot to learn.

i've done a fair amount of looking around for confirmation on this subject, here and elsewhere, haven't had any luck. plenty on heel and toe alone though. there seem to be a good number of instructors here, hoping i can learn something.

your thoughts much appreciated. many thanks.
