This board is intended for the expert. It is flat on the bottom so there is no grove to stabalize lateral rotation. Wich means that you can spin it, kick it, ollie it and rock it.
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.
This is the largest board intended for intermediate to expert riders.
The cylinder is approximately 16.5" X 9" and the board is approximately 14.5" X 48" (four feet). The board is constructed with five stringers of oak with a quarter inch center stringer and six stringers of poblar. The cylinder is crafted from pine. It is all sealed up with poly, and non slip tape adorns the cylinder (not grip tape).
This board is big and fun. It will make you feel little again.
This is the exact same board as The Flatty except the cylinder has a groove cut in it that rides on a spline in the board. This would be an excellent board for the beginner because it takes out the twisting that makes The Flatty more challenging. Also an excellent board for physical therapy as you do not have to concentrate on the action while perfoming another movement.
This board is still challenging and a heck of a lot of fun.
