Also, make sure your staff is weighted properly. If you have too much weight on one side (due to screws and/or wick/pad overlap) then your staff will bounce as a normal part of it's rotation. This is a very frustrating thing and can destroy your learning curve.
For instance, the steve will begin to roll down your arm to your neck, start bouncing due to the weight offset, and then bounce right off your back/opposite shoulder. Since you need the staff roll to control the movement, it's difficult to compensate properly for the bounce.
The best way I know of to determine how well the staff is balanced is to do a clean free spin movement (like a burnoff spin) in front of you with as little verticle movement as possible. If you get enough air time in there you will be able to see how the shaft rotates in conjunction with the wicks/pads. If the staff is bobbing much during this free spin, then it's weight is not distributed well.
Hopefully that helps a bit.
