I'm loving these wheels! I'm using them for long distance skating, really good roll speed, good grip for pumping, soft enough for rough roads and bumps or cracks on the pathways, the lips are slightly rounded witch helps getting out of grooves in the road or going on different surfaces the lips aren't going to get caught, they are also really good at high speed i've got up to about 50km/h and feel i can go faster comfortably. only negative thing is that they are really big so i had to sand down my wheels wells a bit so i don't get wheel bite, but my board is a low drop through set sup, also a bit sleepy in the rain. my last skate on them was about 50k and they were awesome, you just have to get used to going that little bit faster, and having a bigger wheels.
