I only use the XXX brush myself, as it is very low maintenance, and lasts about 50 runs. I make sure I keep it serrated, perhaps after every 3 to 4 runs. The serrations increase surface area and current flow and stop glazing, so performance is maximised. You can run a lighter pressure with the XXX brush and it is also low friction any way, so top speed is very good. The lighter spring Red +ve and green -ve are effective if you maintain a fast speed, as they give less friction. The silver brush does not burn like a cheaper brush. Red is more pressure on the +ve as the electrons have a harder time penetrating the dirty copper conduction layer, but they leap off onto the brush with less effort. For max torque the heavier purple springs keep the brush pressed down to prevent the arcing lifting the brush. Also you may use a sacrificial brush such as the 4499 for more acceleration, but they do burn up, especially on hot days. The higher silver brush such as the 4503, should give more power.
