I would have to keep the 6 speed, it would be so much fun to drive that way.
Side note, should have a lingenfelter(sp) c6 guy calling you guys about an auto swap. Told the dude about you guys on the way home from SEMA and he was sick of the triple disc clutch he said. If he contacts you guys and you get the job, I think I deserve some dyno time on the house.... :-)
