Aluminum bike but I've been told that since I'm a big guy, 6' 215 lbs, that aluminum may not give
me a good ride. I have been told to get carbon or titanium. What is you take on this?

Comfort is primarily a function of fit and tires, not frame material.
Weight: At 215 lbs, a light frame shouldn't be a high priority. In general, carbon frames will be
the lightest, followed by aluminum, Ti, and steel.
Flexibility: Frame flex is dependent on many variables such as tubing diameter and wall thickness,
in addition to frame material. For a given tube diameter and wall thickness, steel will be the least
flexible, aluminum and carbon the most flexible.
Durability: Depends mainly on good design and construction. When pushing the envelope on light
weight, durability usually suffers.
Cost/Upgradability: Depends. In general, Ti and carbon are more expensive. The cheapest frames are
usually aluminum, but there are exceptions. Not sure what you mean by "upgradability," but if you
mean re-spacing the rear dropouts, that is only practical with steel.
What do you expect a new bike to do that your current bike won't? Most of the improvements in the
last 20 years (smoother/easier shifting, clipless pedals, etc.), don't involve the frame. Ti and
carbon frames are lighter that comparable steel frames, but not by that much. "Ride quality" is not
directly related to frame material.
I would choose a frame primarily based on fit, durability, an suitability for your intended use.
