The sign of a good lens is "does it focus Ok from centre to edge when fully open" I have a lot of lens, so printing at 16*12 fully open sorts the men from the boys.

Umm - enlarging lenses are intended to be used stopped down to f/8 or f/11 - fully open is really only for focusing. It doesn't matter that the exposure for the paper is longer, in fact this gives you more time to "dodge". Your print is going to be in the dev and fix for a few minutes, and wash for an hour or so, why worry about "saving" a few seconds whilst exposing the paper?
