I see our pal Spungo's younger brother pretty often, and he's really really good... we were skating after work Friday and he was dorking on a bunch of ollie body varial variations... I can ollie and switch my stance FS, but hadn't got the knack for BS until he showed me... it feels like a one foot combined with a late shuv. Stoked because BS is my natural spin. After a few I was able to get a couple of little variations (like catching it right before landing and turning it all the way around).
One of those little tricks where as soon as you land it you're like "how did I not already know this?"
