Combo list is vintage 2008 or something.
Dunno about a current list.
Info is fine, most of the general HOS mentality won't change much.
*shrug*, many different play styles to HOS. Tactical Inoue, furiously random 0, level 1, 2, or 3 play, heavy oki, heavy rush down; it's all up to you and what you like.
Huge question here and 4r5 would give you a freaking book about it. You have to use spacing, blocking, punishing, and poking to the best of your knowledge; but that is the hallmark of any pro player with any character in almost every situation.
