IME, anything heavier than 531C in a 62-66cm frame feels harsh and "dead". Probably the worst in this regard was my 65cm Eisentraut Limited touring frame. Admittedly, it was optimized for loaded touring (HEAVY tubing) and I was using it as a rain/rando/training bike, but it always felt as if it was actively resisting any effort on my part. A shame, because the geometry and metalwork were wonderful. Just couldn't stand to ride it. I'd love to try a 753/531P/Columbus EL bike in my size some day.
