I like how 16's 'claw' adds more anecdotal evidence to the roller/pinchy claw debate. I also like how it seems to auto-align slightly so long as its center point is within the center diameters of the tubes (looks like surgical tubing that does the work).

My other favorite design that I saw in a webcast was 25's. I also saw this design in person during Battle O Baltimore 2007, though then it was implemented with hockey sticks. It is a simple inner-pinchy claw that comes togeter to a fine point for dropping down into the tube, then spreads out when it's time to pick up the tube. As implemented, it allows for a good deal of driver error (Triangle hole width - 2" or so) and also allows them to drive around as soon as the prongs are inside the tube, regardless of whether or not the tube is picked up yet.
