My first road bike was an aluminum for a year, then moved to a 86 Nishiki Tri-a and got a Centurion ProTour15 (steel) for commute.
Using wider tires for commute is great and super comfy, but somehow the ProTour15 fells a bit heavier (have fenders + rear rack).
Last year I got a TI bike, Litespeed Firenze with carbon forks. Really light but something was not there. Flex? And max tire was a 25c.
This year took the Nishiki to a bike shop to have the rear brake bridge moved some 5 mm up to be able to fit a wider comfy tire on it and added all the bosses for fenders and racks.
Got the paint stripped and powder coated. Now I can fit a 700x32c on it
