What's the grind called that is like a backwards feeble/smith? My brother claims no one does that, but i've seen it in fingerboarding and skate videos.

Second, I fingerboard with fingers tucked, and my hand is at an angle that when I ride, my fingers literally slide across what ever surface I'm skating. I just keep my hand that low I guess. I know everything is preference yada yada, but is that something I should change? I don't see it like at all when watching videos.

The trick is a hurricane

hurricane?

LAWL! Like on a scooter!? (My neighbor is big into those)

hurricane or sugarcane depends on how you get into it and maybe try tucking more or slightly less hope this helps   

Nah gabe how much im tucking isn't the problem, I just keep my wrist really low
