Far 5S against Bandit Revolver is more of a reaction than read i would say.You react during the airborne frames of the move.If you react late c.5S comes out and can punish with the same way as with far 5S.If you react even later c.5S comes out, you both get a counterhit,but Sol is in a juggle state and you have time to go for dash PK combination combo instead.If you delay your 5S even more,Sol gets a counterhit.If he counterhits you crouching he can link into any normal into full combo>knockdown.If he counterhits you standing he can't link into anything though.If you instant block the last hit of Bandit Revolver,you can punish with 4P>1K>2KK knockdown and go for a safejump from there.Same goes for Bandit Bringer.
From what i've seen ,these moves aren't used that much in jp high level play during blockstrings.I think it's important in this matchup to pay attention to any patterns that the Sol player may use during blockstrings.Being able to react and punish stuff with normals,Blitz Shield,IADs,instant blocks is significant in this matchup or else you are stuck in stupid Sol rushdown pressure.
