Same as others have said. Unless you have revs, I wouldn't necessarily go with plastic as a first option unless you were using something like a XXXL or a polished urethane like a Visionary Slate Blue Gargoyle. Dry or not, the ball's gotta have a core.
Otherwise, I'd get something reactive that was very polished and very mild. If you can find a real oldie like a Meteor Storm or one of the Track Sensor balls, then drill it pin way over the bridge, that would be my vote. Those balls had cores, and were very controllable. A Roto Grip Retro Resurrection has worked well for me on those conditions; just make sure you polish the crap out of it first.

p.s.: The buff information is also important to have; if it's 24 feet and then nothing, good luck. If it's 24 with a little buff, you have more options. If it were me, I'd be standing left and throwing as far right as I could go without burning up the ball. Down and in straight up the back would work but it wouldn't be my first choice.
