I feel so much more balanced on these wheels and they have continued to roll smooth since i got them at the start of winter, love the tread makes a very cool noise when you whip around a bowl and when you powerslide, the tread gives a really great advantage on gripping with tight corners over all love them the only thing i could complain about is the weight but thats to be expected when upgrading from 24x110 to 30x120, and since ive upgraded have had to get used to the weight (can double flat again)
