I dunno about a CounterSash set tbh, it just gives up too much mid-late-game utility and seems really situational to begin with.
Anyway Metric, what you have up until now looks good, I'd just make the order on the SD set this:
name: Swords Dance
move 1: Swords Dance
move 2: Night Slash
move 3: Ice Shard / Ice Punch
move 4: Low Kick
Also, mention how you should always use Pickpocket with items that get used up in general, not just Sash (Berries, Gems, etc)
