I think the team to look at (or teams) are 118, 16, and 148. Those three raise the bar/push the limit every time they do a crab/swerve. 111 as well. (Two championships and a finalist on crab/swerve, plus regional wins/finalists, isn't bad.) Weight comparison--can be heavy compared to tank drive.

Now, how to build...Coaxial? Crab? Swerve? (There is a difference between crab and swerve.)

Pros: maneuverability and power and speed in one package to a greater extent than skid/mecanum/omni drive

Cons: may take time to turn, may require a turret, heavier, more complex.

If you're going to do one, start prototyping now.
