Shane's put out some top notch parts over the past 4 years or so that are obviously worth watching for the diversity of tricks, yet the few switch backside flips thrown in them definitely stand out.
In Skate Mental's Am Chowder, Shane works a switch backside flip into a banked manual at 1:41 with enough ease to calmly 180 out at the end. He also nails a really nice one at 2:29 at this foundation gap.
In his going pro video part through Skate Mental and the Berrics (above), Shane continues to show his comfortability with the trick at 0:47 across a flat gap and especially in the combo trick at 2:48, the likes of which I had not even imagined possible before this video part. (Remember how monumental this part was when it came out back in 2010? Looking at it now is a trip because of how much crazier skateboarding has become in every respect. Woah...)
Recently, in Primitive's team video Pain is Beauty, Shane perfectly executes a switch backside flip over a picnic table at 7:52, which again demonstrates the right balance of everything good in a stylish fliptrick.
And lastly, in Not Another Transworld Video, Shane does the trick into a nose manual at 0:53 (holding it for quite some time) and just to be safe he nollie flips out. At 1:39 he utilizes the lily manual pads with a quick ollie up then a frontside 180 switch manny switch backside flip out, fully rotating the trick on its way out and sustaining his momentum too, just because that's how good he has the trick. He immediately follows that clip up at 1:45 by speedily switch backside flipping with a sick flick across a long gap. And then at 2:39 you can witness the culmination of all switch backside flippage with the ultimate ledge combo that I had been dreaming about seeing for years: switch kickflip back tail switch backside flip 270 out.
