I have to agree with you here. We used a suction device in 2007 and while it was successful, to a certain degree, in picking up the tubes, it was difficult to maintain a grip on it while being defended. It all depends on your contact point and surface area for the suction device, but I would suggest looking at devices that did work very well in 2007. Take a look finals videos on the blue alliance for devices that worked under extreme defense.
