Seriously speaking, the Visionary B/G Centaur is the "weakest" reactive ball I've used, with the exception of a long discontinued Claw Hammer.
Urethane isn't that it's "weaker", just different. Normally, a regular urethane (like the Natural or the Liberator) will read earlier than a polished reactive, yet have a lower C.O.F. on dry than reactive, thus not OVER react on dry backends.
Even though "DRY LANE" reactives are designed to help handle lower volumes of oil, they can still be pretty strong on truly dry conditions.
