I prefer a softer compound on the dampeners if running alcohol free. Starting out at 20 shore hardness under most conditions will work a bit better I.M.O.
Im also a strong believer that on the smaller Speedmasters 72, 74, and smaller there is no need to have a crown ground into the water pan roller. Ive found a parallel grind of the roller makes for better water control especially when running the softer rollers.
