Augie B your logic and choices make sense. Update this thread down the road.
For my DeRosa Pro I like the 22mm Conti Sprinters; the previous owner thought they brought out the feel intended for a race bike of the era - that being sharp and precise over comfort, which the frame tubing (60cm SLX mostly) was supposed to deliver.
For the EM Corsa Extra, 25mm Veloflex Roubaix make the 61cm SLX frame heavenly.
Pairing the wheelset/tires to one's idea of the perfectly matching frame is as individual as saddle and color preferences.
edit: tire pressures make all the difference. I run 105/110 on 23&25mm. 90/95psi on 28mm Vlaanderen
