I just had a long talk with my gf about this (we're both psychology geeks), because I'm kind of dumbfounded by this dude...
On one side literally, when he's skating goofy, he rips transition and does gnarly tre's over shit (rails, table tops, bump to bars), and it looks fluent, like he's naturally goofy footed.
Then on the other hand, when he skates regular, it also looks fluent (though to be honest he looks minimally more rigid in a regular stance than in goofy). He does regular kickflip front nosegrinds, kickflip front lips, etc...
A couple more people in this thread alluded to other local skaters they know of who are ambidextrous like this dude... who skate transition in one stance, and street in an other.
What's mind blowing is that I've never seen anything like this, practically no one else has.
We might be seeing a new breed of skating... or not, he might just be a total outlier and anomaly for ever...
...still mind boggling.
I personally think he's more fluent skating goofy, it's obvious when he skates tranny. I think his natural stance is goofy and his switch stance is regular, even though he does regular kickflip fs nosegrinds and kf fs lips in regular... his goofy stance is way more fluid.
You just can't become incredibly good at transition in switch, but you can become incredibly good at street in switch. That's why I believe he's really goofy footed
