Something must be in the juice these kids are drinking 'cause they are just on a tear right now. The latest piece of progression comes courtesy of Stu Shinn: wake-to-wake backside bigger spin. That means his body does a backside 3 while his wakeskate does a backside 5.

Drink up, children… this cup of progression tastes so sweet!
