Well, I forgot to mention that I did encounter a cab that was incredibly slow with the moves too and what not. It was on one of those generic deluxe cabs (the ones that house MvC2), and it had happ parts. It was extremely awkward to get rolling motions out on the stick, force kind of had to be used. And charge moves felt like they would take an eternity to come out.
I honestly don’t know if the type of parts have anything to do with the inputs. QCF, QCB, and dp’s come out good when i’m using jap parts. Must be a coincidence.
