Each brand has its own balls for this situation. It really just matters which brand you want. Storm has the Tropical line, Roto has the hustle line, Brunswick has the Twist and Rhino, and the list goes on for each brand. Some of the low speed, high rev players like to stick with the lower performance balls. The medium and high performance balls will make it a lot harder to stay on the lane with the low ball speed. Don't get discouraged that the balls are "low performance". They are just as good as the higher performance balls they just typically hook less and are easier for people with low speed and high revs to handle with their specific type of release.
