One more thought on this; when Jan Heine says, "If you don't know this, you may expect the ride quality of a superlight, thin wall tubeset, and you may be disappointed", I can't help but wonder if he's thinking of the eighties Prestige Super Lite which had 0.3mm walls. With standard diameters, I'd think for anybody weighing over 175 pounds and/or riding a larger frame Prestige Super Lite would be pretty flexy.
