I would actually give the "aero" nod to the Pista Fiamme rims, not a teardrop, but the rim was a pretty severe trapezoid as presented on a built wheel.

The Saavadra may have been fighting for first "teardrop" aero production rim in the 80's.

As for spoke count, 32/32 is really versatile. I rode 28's in a mass start track race, and I had to wait for the bike to settle under the rims when I pulled off pace and swung up to the top of the banking. An odd feeling... but they were Nisi 200 gram Oro rims and Clement No. 1's, at 9.5 atm. Won the race.
