Matt,
Note the massive difference in pivot locations between these two campy levers. This has a great effect on the feel, maybe even more than the spring tension by itself.

From: "matt yee" <mattmatthew@hawaii.rr.com> ".... I noticed that older sidepull brake calipers have a ton more spring tension than, say, newer dual pivot brakes. ....... Wondering though why there's so much more tension on the springs than the new stuff? Are there differences between the old Italian stuff and other contemporary component manufacturers?"
