The trend for whom? Professional racers being followed by a team car full of spare wheels? Or Clydesdales?

My Synergy rims are 23mm wide. Having seen what a 700x28 looks like on them, I'd be frightened at the thought of trying to run a 700x23 on them! Then again, I wouldn't run a 700x20 on my 19mm ride rims.

I question the judgment of your wheel builder. Why would you want to take a wide rim and install a narrow tire on it? That sounds like a recipe for pinch flats and a harsh ride, to me. You'd probably be better off using a Deep V: it's slightly more aerodynamic than the Dyad, only a bit heavier, probably stronger, and a much better match for 700x25 tires, IMHO. If you decide you need the harsh ride and pinch flats, you can always switch to 700x20 tires...
