I am a 97a devotee, but yeah, skateparks are where these wheels perform their absolute worst, though I suppose it depends on what type of park we are talking about. On a bunch of wood ramps in the basement of the YMCA, maybe they're great. They're definitely a little slower than a 101 on the glass-smooth concrete of a modern skatepark, but they roll incredibly in my local parking garage, asphalt slappy spots, and around the weather-damaged streets and sidewalks.
