I used to skate 50mm, up until they were like 35mm. Right now, my 50 are probably 40 and I have a set of 52 sitting and waiting to be set up. I absolutely hate bigger wheels, even for bad ground, I grew up skating bearing shields, and I still cant skate big wheels. Also, 99 hardness is where its at for me, I had 101 Spitfires once, and they were horrible, at least for me, way too hard. And no skinny wheels for me, also.
