take a look at the Blue/Green Centaur from Visionary. it's a pure solid designed for conditions such as you state. the cover is decently strong, but the core is nice and weak, making a wonderful control ball. the OOB surface is 1000 grit, so you you'll probably need to take it up, add polish, or both. however, with the proper surface, this ball is lights out on medium light oil, over/under, and flying backs.
