Don't let centrifugal force control your bleeders. By mounting your bleeders in the center of the axle axis, these forces are eliminated and allow the bleeder to do the job it was intended to do. If you have ever lost a race because stagger went away, a Conroy Pneu Control will help you regulate it more accurately.
The Conroy Pneu Control Diaphragm bleeder works on the same principal as a high speed by-pass. A preset spring pressure against a diaphragm controls the amount of air that is to pass through the port and it releases air instantly in a 360 degree pattern. You don't have to compensate for what you think it may bleed off at. It repeats within 2/10 of a pound. With 4 different springs, the bleeder has a range of 2 to 30 pounds.
