Um, pretty much all physical SD work is based on the premise that we're not knocked out on first punch. I don't see how that premise changes for someone who's blind.I cannot agree with grappling being the preferred SD method. This assumes they are not knocked out by the first/sucker punch. Avoidance has to be their first line of defense. I know it isn't PC but they are exceptionally handicapped in a one on one SD scenario so the probability of an attack has to be absolutely minimized.
