you ask in an earlier post what kind of power generation the other schools were teaching. At the time I was in GTI (former TAGB) and they were teaching waist-twist and reaction hand. Around that time there was also a very patronising, butt-licking article in UK MA press about someone being taught 'true TKD', not 'outdated waist-twist'.
See how well I block your punches with my jaw!!
