Titanium or Carbon Fiber?
I want to smooth out the ride on my Aluminum TREK.

Thanks!

Lowering the pressure without moving to a larger tire increases your chances for pinch flats.

Do both, get the largest tire that will fit - a trial and error method, THEN use less air to smooth the ride.

All else equal, carbon fiber transmits far less vibration than any of the metals used in frames. Now, there could be other factors that mask any difference, though, such as frame design (tubing, wheelbase, angles, etc.), tires (size, pressure, compliance), and points of contact comfort.

Aside from real suspension, if I were going for comfort it would be a long wheelbase all carbon bike with as many carbon parts as possible, and 28 mm tires.

I never thought about the wheelbase till Doug said it, but I know that both my CF bikes and my Ti bike still don't measure up to the comfort of my old steel bike. I even rode a modern 853 steel bike for a while hoping it would measure up. My old frame from the early 80's has a wheelbase 2 inches longer than any modern road bike. It was designed for 27" wheels with 1-1/4 tires but I have changed it to modern 700x23 and it still rides smoother than any bike I have ever swung my leg over. Steel is also pretty good at absorbing vibration, but the extra 2 inches is what really makes the difference.
