A 20mm tyre on a 21mm wide rim is asking fro trouble. The tyre should at the very least equal the rim's width. Normallly rim width + 1 mm.
That said, I never had any particular problem with Veloflex Corsa be that a 20 or 22mm one. They're light so they're bound to be pretty skinny. Don't expect the impossible and avois glass shards and other urban debris and all should be fine.
Pretty fast and comfy too. Especially so when outfitted with a decent latex inner tube.
Record is just too skinny for regular road use, it's a specialty tyre designed for time trialing.
would a 20mm tire on a 21 mm rim give you the same aero benefit of the wider aero rims that are all the rage
For starters wider rims aren't more areo (not when width is measured where it should be measured when we're talking rim width anyway) and a narrower tyre on a wider rim is about the least aero as can be.

These are clinchers he is talking about. I mounted a 23mm Corsa CX on 28mm MTB rim and it was 29mm wide. Looked rather nice actually.
So within reason, the tire will be wider than the rim regardless. And yes, a 20mm tire on a 21mm rim would be fine. The Veloflexes are not very aero though because of the lip where the tread meets the sidewall. Conti Supersonics are better.

Any tread pattern would potentially generate more turbulance than the mere transition of a tread and the underlaying sidewall structure I'd say.
Conti Supersonics are better.
So you keep telling us again and again and again.
FWIW, I had a pair of Veloflex Records from some track clinchers that I put on some road wheels and put 1,034 miles of hard city road training on them without a puncture. I (knock on wood) don't puncture much, but these tires did fine and were bald when I finally took them off. Not bad for 135 grams. I did have the same luck with Conti Supersonics as well.
I guess I should add I use the Supersonic in combination with a Michelin latex tube.
