There is no difference in the color of the balls between the Tournaments and the Super Pros. The pink 4/12 and brown 7/15 are the TV set. but the standard sets are the traditional colors in both the T's and the SP's.
The Tournaments is Aramith's new top of the line ball. It is made with a new generation resin (Duramith) that is said to be more durable and easier on the cloth (less prone to producing burn marks).
The Super Pros are still a premium set and haven't gone down in quality just because of the new T's. These balls are still used at many professional tournaments. In fact, they are probably used more than the T's unless Aramith is providing the balls and wants to provide the T's for marketing purposes. But the Super Pros are a very high quality ball, the same ball as the Brunswick Centennials except for the graphics.
The Super Pros are available in the traditional set and in the TV set (some balls are colored different to make them easier to differentiate on TV). The standard set comes with the red logo cue ball and the TV set comes with the measles cue ball. Aramith says these cue balls are essentially the same specs and if you prefer one or the other they are available separately as well.
Both the T's and the SP's are matched sets, meaning they are matched by size, weight, color. Also the cue balls are matched to the set (uses the same resin). So the CB with the T's is a different cue ball also made of the Duramith resin.
Both are great ball sets. If money is not an issue I'd go with the Tournaments just because they are said to be more durable and kinder to the bed cloth. But if money is an issue, get the SP's and don't look back. They are a great ball too.
Before springing for the T's though, some have reported they play a little different than the SP's. That sounds plausible since they are made from a different resin. So you may want to do a little research here first to help you decide.
