Holonomic vs Mecanum Help!!

[kSniper]

Hello again, my team has been discussing pretty much every drive train method under the sun (including drift and ackermenn lol) but we have gotten stuck on Holonomic vs Mecanum and have a few questions that if you could help us with it would be much appreciated....

1. Would plastic molded wheels skid on carpet when trying to gain speed or push? How much so?
2. While trying to go from high speed to strafing around a corner would there be some diagnol skid?
3. What is your general thought on Mecanum vs Plastic Molded in terms of stability if we did the / \ design with Plastic?
4. The rubber on Mecanum...I have heard it is horrible for traction on carpet even compared to the plastic of say AndyMarks...is this true? or does the rubber help make the robot more capable of pushing or holding its ground.

And lastly when strafing with Mecanum ive been told you loose half the speed compared to straight aways....assuming thats true do you think thats really a bad thing or would that allow for better controllability?

Anyway if you guys could answer any or all of them It would be amazing thanks....Team303
