Supershifters and Mechanum wheels

[bs7280]

the team I was on had some trouble with driving this year (it wasn't great but it did the job). Having mecanum wheels would have helped greatly in lining up our robot to grab/shoot frisbees and we also had some trouble with speed and getting blocked.

How well does a set of four mecanum wheels deal against being blocked? and how fast could a set of mecanum wheels get a robot up to compared to standard wheels?

Are supershifters worth it? and how would a supershifter on each mecanum wheel do (assuming the money didn't matter)?

thanks! -3734
