Was playing around with jG recently. It's one of my favorite systems lately. If you jG the second hit of Pyrrah's CE you can interrupt with iMCF into a combo since it'll ALWAYS land CH. I wouldn't suggest it since you could just as easily step right, forward grab. You'll get a backthrow every time. But iMCF looks raw. You have to do a jG, then do iMCF, and you have a 3 frame window to do it.
