I think it was true a looooong time ago when the only sizes you could get in good quality casings was 20 or 21. But that is a long time ago.
Especially with the dreadful state of roads in recent years, then any gain is lost anyway by time to repair punctures...

not 25mm but they look good for £27 all in.

Quoting the immortal Sheldon Brown:
"Most people find expensive tubulars too expensive for recreational riding...but cheap tubulars are distinctly inferior to good clinchers, particularly in that they tend to be lumpy and crooked.
Comparing high-quality tubulars with clinchers, including the rims, tubes, etc, tubulars save about 50 grams per wheel...but your bike winds up heavier, because you really need to carry a complete spare tubular, as opposed to a tube and/or a patch kit. This doesn't apply if the team car is carrying spare wheels/bikes for you.
If you don't glue your tubulars on properly, they can roll off, causing you to crash. If you get a flat on the road, you can't glue your spare securely, since the glue needs to dry overnight; as a result, you have to ride very gingerly on your spare, taking it really easy on the curves and descents. If you get two flats on the same ride, you're screwed.
Some people believe that tubulars corner better in the rain...but I never go fast on wet roads anyway. If you flat in the rain with tubulars, your ride is over, because there's no way to make a wet tubular stick to a wet rim.
Tubulars are fairly immune to "snake-bite" rim cuts, and may offer slightly better "suspension" action than comparable clinchers. Their rolling resistance is actually worse than good clinchers in most cases, due to flex of the glued section"
I'll confess to have never ridden them myself, on account of my large frame - but they scare the bejesus out of me in any case. Glue for godsake? For a showcase/period correct/Track bike (period if its that old -clinchers have been around for decades) I'd fit Tubs, but for a bike to ride I'd go clincher any day of the week. Tubs get very expensive if road riding as well.

I should add that my original point also factored in the state of the roads in the UK!! They were bad anyway - post the snow we had recently, they are REALLY bad!

That kinda tallies with my natural inclination... plus there are so many nice classic looking clinchers available now!
Were there clincher rims in 1977? Can anybody tell me which ones were nice? And (crucially!) is it possible to just swap the rims over, or is a 28" tubular rim a totally different size to a 700c road rim (as in brakes won't work, new spokes needed, etc)?
Argh!
