The age old cell question?

What do you guys think of running 10 cells in a lightweight race BL maxx? I think the XL3100, XL3600 or an 8L would be a nice canidate.

I think 32-37 mph is just about as fast as you'd really need to go at the track. These speeds should be achieved with 10 cells along with enough torque.

I have an 9918/8L and will probably try this. Has anyone done this or is it a bad idea?
