I hated my Ideale 80 - just didn't fit me. I love my Brookses (2 B17s and a Pro). But the Ideale was 30+ years ago, and the Brookses are now. Seems to me the Ideale shape is more round in cross-section, and the Brooks is flatter. FWIW, my taste in plastic saddles is similar: I LOVE my WTB SST - broad and flat, like a B17. Can't stand most Selle Italia offerings. Too much like straddling a steel pipe.
