I guess I'm going against the grain here.
I was on a set of radial slims 52mm 101a for about 6 months or so. Overall they were great. But recently I was skating this spot where I was landing sideways in a big crack / seam. I landed bolts like 10 times and kept getting pitched because I could not roll through this crack. Right then I decided I wanted a little wider wheel next time. Also, I found that I'd be going fast and just try to carve backside and I would start sliding. Although it's kind of fun to lose control and then regain it, that is not what I want from a wheel.
So this time around, I got some conicals. 52mm, 99a. So far, I'm loving them and think I've found the perfect wheel. It's only 1.5 mm wider than the slims, so it's still skinny enough. And they still slide great for powerslides or nose/tail slides. But I'm not just losing grip out of the blue like I was with the 101's.
