Thanks...A great link...it nicely summarizes much of what I've read on this site about the pros and cons of various frame materials and wheels...
Do non-competive riders really want 0.4 mm thick steel tubing?Continental

I agree with the premise of this article, but I think that even many steel frames are becoming stupid light. These very thin tubes are strong, but they dent very easily. I'd rather have a few hundred grams of additional weight to achieve a rugged, durable machine.

The bigger issue is not denting but stiffness. The newer steel alloys are stronger, but not stiffer. So, a frame that uses 0.7/0.4/0.7 tubing will be quite flexible under larger riders and/or riders carrying gear. The end result can be squirrely handling, chain rub, and high-speed shimmy.
