I have had other 'regular drop' carbon bars.
The FSA Compact fits me better and adds more hand positions.
I built up a new Look 586 SL frameset to replace my Look 585. The biggest improvement over the Look 585 was adding this bar and FSA stem and my new Fizik carbon railed saddle!
Rode the Seagull Century with the FSA K-Wing recently. Flat section on the wrong is dramatically better than regular handlebars. Very comfortable. Cables rib through grove in the bottom of the handlebar, so clean. Indentation in bottom of bar where my fingers curl around the bar is a surprise plus. And I've found I much prefer the compact drop. As a 60 rider the lesser drop is nice.
