Lower numeric. I don't know anything though. I think you would want to figure out what gear would give you the best cruising rpm for your desired cruise speed? Like say you want to go 70 mph. Then work backwards (or actually forward) from there to figure it out. I've got 3.55 rear gears I think and at 70 mph I'm seeing 1450 rpms (about). I don't know what the 10th gear ratio is on a Eaton Autoshift 10speed is though. I wouldn't mind being closer to 1300 rpms at 70.
