what's the deal here? It's the DJ flip (sort of d-spin 630 to flatspin 450) he's been throwing for more than 3 years. Which is just one variation of how to throw a dub flip/dub cork 10. He's trying out the jump, not claiming anything new.
And yes, Mike Wilson was the first throwing dub 10s in competition, though his "wilson flip" looked more like a rodeo 5 to sw rodeo 5. Not really the same as Jons DJ flip.
