Are all the 3g shoes (tour ultra - sport ultra/deluxe the same except for the slide/heel that comes with it? Or is there a different feel to them?

I have a pair of Tour ultra from the dynothane days and they feel great, but I''m liking the red/black on the sport deluxe.

BTW if I do Tournaments I will have to by the 3g version? I remember reading that a long time ago, but haven''t kept up with it. And what type of tournaments? USBC?
I''m sure most local tournament are not going to care unless it''s sponsor right?

Thanks
