With the advances in tubing shapes and the alloys being perfected the aluminum frames are very competitive for many of us. CF can be so fine tuned with the layering, different fabrics and the binding matrix that you can pretty much fine tune things to each specific usage. I love my CAAD 10, the hydroforming to achieve the interior tune profiles has given the aluminum frames a shot at being much less rigid and stiff or buzzy. The 10 4 has made me a very happy rider and I would jump at the chance to have one of the Allez top end models or the others available now from other mfgrs. I don't see it dying off at all. Steel is here to stay, the newer alloys are super and the weight can be trimmed with them. Titanium is in a class by itself, to me, that would be so neat in a custom made frame.
Good times, indeed.
