There have been reports that 7900 is fussy about set-up and not as slick as 7800, due to routing the shifter cables along the bars, which doesn't seem to have worked out as well for Shimano as Campag and SRAM. Some pro teams have switched back to 7800. For racing (and crashing), I'd go Ultegra if I were a Shimano type of person. The performance difference is tiny compared with the huge price difference.
