If it is for a THS, then the HyRoad is a great ball along with a Torrent, depending on what type of look he wants. HyRoad is more in the backend than the Torrent which is smoother.
The Hustle Ink along with the Match Up Solid are good weaker choices. The Code Red with some surface and the Phaze II would be good steps up. Code Red for those who like asymmetricals and Phaze II for the symmetrical crowd. Downside is the maintenance required on the Phaze II.
On the Roto Grip side, the Dare Devil Trick is a more current !Q Tour. The Show Off could be good, but surface will be very important to keep exactly how you like it to keep it consistent.
