Hey cjh,
Is the Equation enough? This depends on the amount of oil you personally encounter on your THS. Your choice, with the Equation, it will most likely force you to bump against some friction to react unless you are highly rev dominant.
I'd look into another piece that offers you a little more natural strength against the oil line. Our Kinetic is an awesome ball, I "just" recently got a chance to test it some more and I could play it anywhere from 20 (with my feet to 38 with my feet on my THS). Hope this helps some...
