The most effective 6-cim single speed drivetrain I've ever seen was geared to 10fps adjusted. 16fps is in the upper end of high gear for most 2-speed drivetrains I've seen (unless you're from CA, where time must move slower or something).

You might get away with 16fps in a game without much defense, but as soon as you try to drive through another robot you'll regret it, I think. A simple way to test this is to design your gearbox with a "VEX reduction", or an 84-tooth ratio. That way you can swap between ratios to find what you like best.
