Re: robot speed
To stay on topic --
The whole speed vs. control is greatly recognised in an FTC match. Many students, when left to themselves, design their drive trains separate from the rest of the robot. So maybe they design the bots to use the large wheels with a 1:1 ratio or tiny wheels with only 1 motor per side. Then they add all of the mass of the steel and nuts and bolts above their drive train and get very lackluster performance out of it.
This is why I think that if you must go single-speed, 10fps is a good speed to aim for in FRC. Smaller wheels give you slower speed but more torque by design, and combined with a medium gear ratio will allow for decent accleration with only 1 motor per side after you've added all of the weight above it. If you make it 2 motors per side, you might even win some pushing matches.
