A robot that gets a 1.2 coeff on the HDPE will beat a robot that gets a 1.0 coeff on the mesh... the mesh is easier to get a good "grip" on, but there are plenty of teams that have taken the time to "grip" the HDPE just as well, or better.

The mesh has texture, the HDPE does not. You can't grip the HDPE, the most you can hope to do is increase your normal force with a suction cup (and I don't think the HDPE will be in good enough shape to allow this to work as well as some teams think it will).
sevisehda: I said upwards of 40 lbs, I agree that its unlikely someone will be able to carry 8 stacked bins. I do think the angle helps the robot going up the ramp, its hard to tell though. Regradless, most robots will be able to push most other robots off the top of the ramp. I doubt any robot can withstand the force of 2 other robots trying to push it off the HDPE. Only time will tell.
