If I had a garage, my RC200 would be its queen. I dont so take it out ocaisionally when the conditions are right so as not to muddy (too much) the white tyres. I am also not toocomfortable on riding it any where too rough just yet, the thought of damaging some of the bits on it is still a huge concern.
My Marin has pretty much been placed in retirement, it offers nothing the others cant do, but its mine since new so I look after it.
My others all get used though. RC100 for street riding, epic for distance, KHS for clowning around on and the epic for longer rides and tom foolery.
