The way i see it...
Ao & USO should be Medium paced courts. Don't particularly favour any style. If possible, you could have one thats medium fast, and one that is medium slow
Wimbledon should be fast, which favours offensive tennis
RG should be Slow, which favours defensive tennis
USO should be fast, like it was. AO: Slow/Medium Hard Court med/high bounce, FO: Slow Clay high bounce, W: Fast Grass low bounce, USO: Fast Hardcourt natural bounce
