...of course. just like how you, as a Jiggs mainer, know how spamming random down-B's are a reasonable strat.
EDIT: i'll test it more later, but I just was on corneria, and i realized that you can chainthrow backthrows against the wall on the right. it seemed to work until 40% against Marth, but then again you may be able to tech upwards out of it. a normal tech doesn't break the chain, though. mind you, it was against a computer :/
EDIT #2: I was wondering, is there any advantages on doing >B, double jump, up-B v.s. double jump, side B, up-b?
