just to get this thread back on track and give my own opinion r.e: MDMA. he coached me for abut 5 months where I went from 2/4 - 10/20 in basically consecutive months and I learned a TON. we stopped after that andI had another good month pretty soon after:
clearly he was holding my back by the 10/20 stage but w/e, great guy in my experience and an excellent coach.
