Just switched over to FSA oversized bars, low rise with a Thompson stem from my Easton EA50 and Easton bars. Now, is the increased stiffness and "postive" feeling that I notice from the Thompson, the bars or both? I use a Reba Team with the pop lock so I do stand and use the bars as levers more than if I were just riding seated, so yes, these oversized bars do feel better to me. I would not run out and spend $30 to $130 for oversized bars - aluminum or carbon - unless you are in the upgrade mode or replacement with new stuff mode. My FSAs are aluminum and cost about $60. The FSA carbon bars were twice the price and although I could afford it if I chose, passed.
