I'm not sure you can extrapolate from single racers to tandems.

Part of the reason they're going to 25mm tubulars is that they have a good aerodynamic profile with wider rims, such as Zipp firecrests.

28mm tire on a convential (i.e. narrower rim) is going to have a significant aerodynamic disadvantage that you're not going to make back in reduced rolling resistance.

Hence if the goal is performance, you're ok with the ride quality, and you're not pinch flatting, I'd stay with 25mm.
