Anybody have some experience with all three?

I'm the Guinea pig at our local track, 365 ft banked asphalt tri-oval capped tires.

If anyone has some real life data they could share I would apprecaite it.

Bob, when I as how to gear a 13.5 1 cell verses 21.5 2 cell for Easley, Bush stated to gear the 13.5 30 to 35 points higher than the 21.5. that is gear ration not Rollout.

at easley we are very close to the same in 10.5 single cell and 21.5 2 cell
