I do like [MENTION=469351]bark_eater[/MENTION] "bottle of zen" sentiment.

the blind test of steel frames from different tubing has been done and documented, experienced riders. Results = riders could not pick tubesets.

However, the effect achieved for each riders' preference is what I call grail. As much as the name on the frameset.

My experience is primarily with Reynolds, Columbus, some Ishiwata.
[MENTION=551236]DanseMacabre[/MENTION] - can't comment on Vitus, but the 'planing' effect I have observed is mostly on vintage frames with longish chainstays (42-44cm), and I refrain from calling them touring frames. Merckx in SLX a cm or 2 above my 'perfect' size had that feeling. Same with AD Vent Noit (531), a tiny large. My Ishi022 bikes nice but did not plane; would liked to have ridden 019 in a 'non-racing geometry frame'. I have also ridden 'whippy' bikes, that went beyond souplesse.

I ride 60cm frames, weigh 190 (86kilo) - I think I cannot speak for characteristics of smaller framed bikes or lighter riders.
