The Flatty: $99.95
This board is intended for the expert. It is flat on the bottom so there is no grove to stabilize lateral rotation. Which means that you can spin it, kick it, ollie it and rock it.
The cylinder is approximately 11.5" X 6.5" and the board is approximately 9" X 32". The board is constructed with three stringers of oak with a quarter inch center stringer and four stringers of poplar. The cylinder is crafted from pine. It is all sealed up with poly, and non slip tape adorns the cylinder (not grip tape).
This is the most advanced (fun) board. It will encourage you to play on it often and develop new tricks. A heck of a lot of fun.
