If I hit a 22, freeze, I'll more than likely just use jip, b121 and then use the throw mixup or blockstring. I do b1, slide and b12 for the safe jump if the 2 connects, which is just another throw mixup.
This pressure is actually better offline than online, however, because b1 will whiff quite a lot on a crouch blocking opponent after b121 online due to the messed up timing.
I don't see the point in b2 cancels when you have all these other pressure options available off a 22, freeze. You can go ahead and do it when you have Xray but I'd still rather just hit him with the Xray combo off 22 freeze if I am looking to use the Xray. I prefer the Xray combo to be completely guaranteed rather than giving him a 50/50 chance of getting out of the situation and then making one good read and making me use meter for breaker... Since I only use Xrays to close out rounds and matches I am never really looking for the absolute highest damage Xray combo with Sub. He rarely needs it since the basic Xray combos already do close to 50%, and doing a b2 reset will not stop your opponent from breaking if he has breaker.
Those are my thoughts on b2 cancels.
