San Marcos Rolls are my favorite for 80s race bikes, and Ideale 90 for tensioned leather. I tried Concor, Regal, Cinelli Volare, Turbo, Flite, Avocet Racing, and maybe a couple others before settling on the Rolls. +1 to @Chrome Molly. His comments in post #38 re Rolls are spot on, and/or our butts are similar.

Currently, I own:
Avocet Touring-I
Avocet Touring-II
Avocet Touring-WI
Avocet Racing
Ideale 80
Ideale 90
Ideale 90 with alloy rails
San Marco Rolls
Selle Italia Turbo
Selle Italia Flite
Wrights W3N

I always rode plastic-shell leather saddles until I found this forum and began collecting vintage bikes. Now I have a new appreciation for tensioned leather saddles. I've been really happy with the few Ideale 80s and 90s I've owned. Confession: I've never ridden a Brooks. I'd be curious to hear comparisons between the Ideale 90 and a Brooks Pro from people who have tried both. I'd love to try a RHM special one day, too!
