I geeked out and checked the sessions on that 10 stair hubba to flat ledge @ :47 in Flora--
he's in the same getup for 2 of the 3 tricks on the same ledge in Blue Dog (@ 2:06). Same lighting, too.
So in that single session, he did blunt to back 50-50, back tail to back tail, and back tail bigspin. I guess he figured he'd save the best for last?
