I recently switched from a WSB Touring saddle to ISM - I actually got two, one for my Jamis Renegade and the other for my Bike Friday. I maintain a non-racing posture (not fully upright, not down on the drops) and found them both comfortable. I think I got the PR 2.0 and PR 3.0 with padding levels 40 and 60. I moved my WTB Touring saddle to the tandem.
