I haven't ridden them, but there are a couple of sets of them at the shop... they look fucking amazing... like they're made out of honey. They'd be perfect on a Zip Zinger or something similar, as they're light, they have a smaller diameter so they're perfect for a smaller board, and they're squishy soft so you can roll on top of any kind of terrain. Shit, I may have just talked myself into getting a set.
