That vortex is really neat. The 2b cross-under seems a little too slow to actually catch somebody blocking the wrong way, but coupled with the possibility of either a low or a high, it might overwhelm people. Have you tried it in matches?
After you condition them to tech or die by 2b, doing the 2d (also has the option to cross-under) seems like a decent option. It's reallllly open to all sorts of things after your opponent sees the 2d-> jump cancel, though. There's a lot of time mu isn't doing anything, but you can use j.2C to CH anti-airs, and if you do cross-under -> jump cancel 2d backwards to cross-up, it's really obnoxious to try and actually do a 6A, let alone a DP. Unfortunately, the timing on the laser serves less to cover your landing and mixup attempt and more to mess up the combo if you hit them Not every time, though, it can be made to work. More experiments tomorrow.
Edit: last test for the night: if you do XX > 3C > 2B > 5C > 6C > stein > 66 2D cross-under > jump backwards, 236D, you land right next to them with a laser hitting them twice. Still really open in the air, but if you can get someone conditioned enough to freeze them up, it's another option.
