Good wheel to start out with when learning slides.
The hard durometer and round lips allows for this wheel to be easier to kick out when chucking out slides.
The downside is that they can feel a bit sketchy to some when freeriding at higher speeds. The hard durometer makes the wheels slide feel icy and less controllable as opposed to a more buttery, controllable slide you would get from a wheel with a softer durometer such as 78a or 80a.
