Try this.
Go borrow a BMX bike. Try to do the same tricks you are learning now on a fixed. You will learn them in less than a week. Why? Because BMX bikes are mature. The ideal geometries have been worked out. The best of breed parts are out there. There are even bikes that are specialized for street, vert, dirt, and flatland all with different angles and components.
Oh...and the parts won't break during that 3-set you just dead-sailored.
