All the balls you mention are sensitive to oil and can become over/under very easily.
Have you considered a Hustle INK? The HSB looks good in my partners arsenal but he has less tilt than I do. I see all the people with Au's getting rid of them .... big time over/under.
The Tropicals are decent, but get a hybrid if you go that route. They are less ball than the Hustles. Reactor coverstock is clean and reacts to friction well. It would be the longest and most sideways ball of the bunch.
