Rainsport 2s are great on my OH Fiesta ST, great in the dry, phenomenal in the wet. Not great on high loadings though (92Y for instance) granted, but good for the smaller car.

But in 195/50/15 i'd go for a nice cheap toyo t1s that are nice and soft n grippy. At £30 odd a corner you can afford to replace them whenever it's needed for track use, but not that great in the wet.
