Hey Will thanks man! Yeh I know this video very well, I cant believe how easy Stepane makes it look and in 1998 as well, unbelievable. I was talking to another old school rider from Thailand, Lota who used to compete with Stephane, he said he stopped doing the double sbend after he broke 3 ribs on a crash. I think thats why you just dont see this trick being done these days, even with the much bigger wake.
Ive only seen one other video of Dustin Shows here at 1:20
