Well put Bruce. I do agree they are all good bikes! I would guess some riders are more sensative to differences than others.
On rougher surfaces, the tires size can make a big difference in how much vibration the rider feels, less noticeable on smooth surfaces. After riding the infamous Texas "chip and seal" roads on 25/28mm tires, 35s feel wonderful. I can't immagine riding 21s on these roads like the local racer crowd does... I have ridden my All-Rounder and Rambouillet with the same tire widths and the bikes still feel different. Narrower tires "felt" faster than the wider ones, but the bike still felt more less nimble/more stable than the Rambouillet. On the Quickbeam vs the Atlantis (64cm) the HT angle is 0.5 degrees different and the chainstays are 1cm different. With tires size within 1mm (measured) I can hardly feel a difference. Of course on the Quickbeam the rear wheel moves back and forth when changing gears and I can't tell any difference due to that. All the Rambouillet talk has inspired me; the rain stopped, the temperature hit 60, I'm goin ridin!

Yep. If I had to only keep one of mine though, it > would be the Ram.
