Hi again guys o/
i was messing around with ext inf and i got a lil variation, a twisted infity ^^ its breakdown:
- Wiper Reverse T1 > Pass Normal T1-23 > Sonic Normal > Wiper Reverse 12 > Pass Reverse 12-T1
It really looks like an ext inf that starts on T1 and do the charge on 23.

From this onde i took the "thumb less infinity" ^^ breakdown:
- Sonic Normal > Wiper Reverse 12 > Pass Reverse 12-23 > reeat
I'm not sure about this breakdown, but i think you'll understand it xP the sonics need to be done holding only the tip of the pen (as you do on an inf) and you'll need to wiggle your wrist a little to get the circular motion.

Here the videos:
Twisted Infinity
Thumb Less Infinity

Wiper Reverse T1 > Pass Normal T1-23 > Sonic Normal > Wiper Reverse 12 > Pass Reverse 12-T1
- Looks familiar, I've probably seen it in a combo before, or even done it myself when messing with Wipers and Passes.

Sonic 23 > Wiper Rev 12 > Pass 12-23
- Definitely not new, I love using that combo in class.

There's no need to name either of these combos, there's nothing unique about them.

Thumbless Infinity would be doing an actual Infinity without using a Thumb. Example:
Wiper Rev 23 > Pass Normal 23-34 > Wiper Rev 34 > Pass Rev 34-23
