On carpet, I've been using grey rear and coral front, I also recently tried coral rear with magenta front at Mike Haynes' suggestion and REALLY liked that combo. The carpet was really grippy that day, and the coral rear magenta front combo was aggressive and fast, with no hint of traction rolling. Thanks Mike!

On asphalt, (360 pulled up the rug last summer and we raced on the asphalt underneath) I ran magenta rear and purple fronts. Worked very nicely. 360's asphalt is ultra smooth and grippy... you might want to look at something different outdoors, or for less pristine asphalt... maybe pink rear with purple or magenta fronts to get the balance where you like it.
