Wow horrific voice typing which one is better a grinds and how does it fair at horizontal
Any of the blasted finishes are great for grinds, whether it’s the QV or Standard Kuntosh, both are great.
As for horizontal, how good are you at horizontal play? I’ve seen people do some awesome stuff on high walled yoyos just fine, IMO the yoyo is second place in that category, first place being your own skill. Maybe someone else can reply to that part.
And the hardcoat finish just curious?
Really, really good 
No idea about horizontal, but the blasted finishes are best for grinds. Probably avoid the hardcoat if you like grinds.
The hardcoat is blasted in this case, but yeah probably doesn’t grind quite as well as normal anodizing.
