Re: 2-Speed vs 1-Speed drivetrain

So this year we ran a two-speed 4 CIM drive with auto-shifting, geared about ~11 in low and 16 or 17 in high, on 4 inch wheels. With the current auto shifting setup, would it be beneficial to make the low gear lower to accelerate faster?

In 2015, we plan to run faster (add additional motors also), with the intent that our 5th year driver will be able to handle it and he wants to.
So what was your 2014 setup like? I didn't see it to much in the pits, but it was definitely one of the fastest robots I saw this year.

So would an ideal system (barring weight and other limiting factors) be a 6 CIM two-gear drive, the low being only used for pushing, and high gear for everything else? I think this is what 254 used this year.
