I filmed on pocket winkler recently, and I was quite happy with my video until this came along and made me, and probably everyone else, look crap on these in comparison.
Haha, seriously though, this is some mindblowing stuff from Mike S! Tricks on a pocket winkler is taken to the next level here, he uses it as a full pipe, a grind ledge, conventionally, and probably other ways too! Soo many nice tricks, you cant miss this.
