|For vert, modern skateboarding wheels rules!!!!! all sizes/hardness/prices available.
I like Powell Bowl bombers 64mm PF (Park Formula) or other brand 60mm+ in Park or Street Formula: very hard and still grippy when you need and still sliding ability (with less flatspoting than classical formulas, good for unlocked plates grinds). Very fast on smooth ramp!!!!!
The centered core gives more precision (not too wide also) and rounded edges slides faster on the coping 50/50's (easier to engage/disengage on the coping also).
