Just something, that while having already been said, cannot be said enough...
I got a stick right around when ST came out. It was my first stick after years and years of playing Alpha and MVC2 on pads...
It will make you a lot worse at first. You will not be able to do things that you usually do with ease. Its a crappy feeling, and then you start worrying that you blew 100+ bucks on something you will never use.
My advice: STICK (haha, see what I did there) with it!!! After a week or two of serious play, it will start to feel natural. I adore my stick, and now, if I try and play with a pad, it just feels wrong.
After a few months of serious training, I am now able to do things with the stick, that I was not able to do consistently with a pad!
