This was my feeling as well. I was on the borderline btw 52 and 54 for my road bike frame as well. Made the mistake of going with the 54. Fortunately I was able to swap that out for a 52. I’m a bit leggy with a 32.5 inseam, so the reach is what gets me. I passed on the 19”
I’ve got a line on a ‘92 720 that appears to be a 17”. I think I’ll check it out this week
