Jacked curl, I believe.
Trompillo's Nest trick uses the same hold but does not go into a curl.
ya i remember seeing that in his patch video, that trick seemed almost impossible the first time i saw it lol
Joe Purdy does a move similar at 1:19 in this video, but you go over when he goes under. Both nice moves.
your wealth of resource knowledge is invaluable sir, i cant believe u remembered seeing that one trick in that whole video lol. it appears from that video that he's using a bearing tip and actually grabbing hold of the tip with thumb index and middle fingers as apposed to fixed tip grinding it on the finger nails of the index and middle, ha! ever so many variations of things lol
and thank you for the compliment sir @-@
