Lol you know whats funny is i was actually working on this EXACT same setup last night. I was doing this though.
njp,f4,dash,2,sweep, f3 etc. The 2 is really inconsistent so i just left it at njp,f4,dash, sweep, f3 or whatvver poke you choose etc.
But then i realized you CANT beat njp,f4,2,2,244np.
IMO you can use it everynow and then? Ill use it.
