Suction cups will work good for the first few practice matches and maybe some into the qualifying but by the time finals hit that HDPE will look like a scratching post covered in dust, dirst, and oil. Everyones pro-suction point is saying they can withstand exert a huge force on a glass-smooth surface, chances are the HDPE will be more like a rough concrete. If teams still want to go with suction cups it seems logical to go with 20 small ones instead of 1 or 2 large ones to minimize the risk of trying to lock onto an area with a scratch.

Do you want to take the chance that during finals your bot trys to lock onto the joint between the 2 pieces of HDPE and another bot knowcks you off like you weren't even there?

Also Ramp-doms have to stay for nearly the entire 2 minuts and even if the scratches only allow a slow leak chances are the ramp-dom would have to re-attach every so often.

The best option is to put some _ _ _ _ _ _ _ _ breaks on the bottom of your bot and get a COF of about 2.0 or if your budget allows and you can find it get some _ _ _ _ _ which will give you a COF of about 3.5.
Friction brakes are more reliable and lighter.
