Yes, but switching from a pad to arcade stick is essentially relearning how to play the entire game again. Tho in the end, you'll benefit from all the effort spent. I learned this lesson twice. Once with psyvariar 2 on dreamcast - switching from dpad to stick, and then a 2nd time when I bought myself Futari without having had a stick for 360. Tho the 2nd time around it was much easier to adjust.
that's why I tend to recommend a seimitsu stick. It has less deadzone than most sanwa's and the tighter spring allows for more precise movements, as opposed to the buttery feeling motion of a sanwa - which is perfect for fighting games. To be honest, I wish they were still going to make the hori real arcade pro ex-se radiant silvergun edition, because I probably would have went out and bought another stick.

hopefully they changed their mind.
