Definitely not, have you ever done switch back? They are super easy and, though I have never felt inclined to do double, i imagine I probably could if I tried. Whoever said switch trip front may be correct though, that shit is retarded. Literally.
switch backflips are surprisingly mellow. you can see you landing really early. i would have to say byron wells' flat 5 at the end of the grand bizarre park seg on what had to be the scariest takeoff ever.
i know a few people have done switch lincolns which are just stupidly blind, but has anyone ever done a dub switch lincoln? i think that would definitely be up there
