Building a second robot - electronics?

Certainly infinitely better than not having two fully-functioning independent robots, but I have it on good faith that there is a noticeable difference in the response curves of the Victor 888 and Victor SP. Looking at data helpfully provided by 1718 here, the 888 does not have a linear response curve (look at Victor 888 cool, not Victor 888). I don't have good data for the Victor SP, but I would assume it has a linear response curve like the rest of the more recent motor controllers. This could likely make a difference in driver practice and autonomous programming for small movements at low voltages.
