You could go with a Brunswick Groove (not the Power Groove, which, for some inexplicable reason, seems to hook the building for everyone I know who throws one). The Groove has a urethane cover and a simple 3-piece core, so it definitely won't be uber-aggressive. You could even polish it to get it through the heads cleaner and give you a hair more pop on the backend.
