I made a switch to SRAM ( 9 bikes ) from early Campy Record, Delta brakes 1991 year (and still museum quality) to Shimano XT, Ultegra, Dura-Ace, XTR, lower end Alfine hub, 105. SRAM Force was the ticket, liked the somewhat heavy ka-clank shifting, Dura-ace like brakes, aesthetics, quality and precision.
Force isn't cheap and uber light but every future bike I will get will have the latest greatest Force Group.
