I just made the decision between CF and aluminum in purchasing my CAAD 10, the CF bikes I tried were so light and in most cases very stiff, so is my new scoot. I chose Aluminum because it stands a better chance with my clumsiness of surviving for 10 years, my minimum time for a bicycle to last me. My R500T was a 97 model and now my son is enjoying it, for goodness knows how long. The CF bicycles can smooth out seriously rough roads and I suspect the CF fork on my CAAD 10, along with the SAVE frame spec do a lot of the smoothing out on my bicycle.

I work with a former, retired nuclear industry metallurgist and failure analysis guru, I grilled him relentlessly about aluminum alloy properties and CF materials he has knowledge of before I decided. Just doing my due diligence. CF could work for me if I strictly raced or fast recreational rode, I am sure. Many friends have CF bicycles.

As said, I suspect this is a troll, if you read as much as you said and then just set up a question to bring out an argument then you loose in the 50+ forum. We can discuss this rationally and see the good points to steel, CF and aluminum as well as titanium, or any other alloy of polymer that is out there, as well as the negatives we have experienced. YMMV
