Barely used set of Arbor sucros wheels I took off a complete deck when I got a new set of freeride wheels.  I rode them only a few times and verry lightly at that, no sliding.  They are not broken in however they seem like they'd be quite easy to break in with a good sliding or carving session.  Others who have ridden the same type of wheel commented on how easy they make low speed slides because of their small contact patch, but i've notice they will grip acceptionally well around a hairpin turn.  They have the obvious road dirt you get on any wheel from riding but thats all.  These are definitely a good beginer wheel, and if you know what your doing you'll be able to do great things with them.  I'd definitely put these on a carving board or any board you don't want wheel bite.
