Our team this year is trying to pick up the game pieces with suction cups. if any one has any suggestions on what we should use or what size we should use, or the advantages and disadvantages of using suction cups. Any help would be great!

IMHO, I would suggest you not use a suction cup, but that's just my opinion. You still have time for a simple pneumatic claw/grabber.
Good luck,

We have tried suction cups before but the surface of the tubes is not excellent for it. There are creases and rounded areas that make it hard to grip. I believe it has been done but it isnt easy

Suction cups can work in certain situations. Running around a field as fast as possible while picking up pool tubes isn't one of them. I saw a couple of teams try them in 2007 but the weren't what you'd call reliable.

Good luck!

We tried some of various sizes with a pneumatic based vacuum generator hooked up to a shop air compressor. The vacuum generator can generate a near perfect vacuum and they were still very easy to knock off.

Has anyone tried to use shop vacs and just mount a fisher price motor to it

They just don't work on these tubes. Testing in 2007 suggested that no matter how much suction you could get, it is much more reliable to use a physical claw or grabber. Don't fall into the trap of using them.
