Interesting and responsive to the question asked? Yes. However, I'm not sure how helpful it is for anyone, to be completely honest.

With few exceptions, the fastest and strongest teams whom we know don't ride the latest, greatest, or most lightweight equipment. In fact, perhaps the strongest teams ride older Santanas... one that was picked up on Ebay. Yes, one of the stronger couples rides a Calfee (older, traditional design), but they're just as fast on their Co-Motion Speedster Co-Pilot. Another A-team team rides a Taliani and they kick butt even when they're pulling their daughter in a trailer, and well, you get the picture. There are Burley Rivazzas and coupled Meridians in the A-Team fleet along with other older Santanas and of couse the ubiquitous Co-Motion Speedsters, Co-Pilots and a Robusta or two.

Building-up and riding lightweight tandems and bikes has it's merits: it's intersting to see what can be achieved and they do feel more lively. However, when it comes to the King of the Hill, county line sprints, time trials, and being the rabbits, it's the motors that make the real difference. So long as the wheels stay on, fast teams are just fast on whatever they ride.
