Dissadvantages of Suction?

[j.cole]

Weight is one thing (compressor, air tanks) unless you already have a pneumatic system in play. Another is reliability, will it always grab the tube. Strength, if you get pushed is the seal going to break. Maintenance, leaks air hose coming undone.

Everything has its advantages and disadvantages so in the end its your call.

That was our main concern when reviewing suction. Personally, I doubted that it would work. But the tubes stuck really well (we had one person hold it up with a venturi while other people acted like robots and tried to knock it down) and it sealed perfectly as long as we had a high enough PSI
