Components: Shimano Ultegra vs. SRAM Rival

[TxDoc]

I can't afford Campy at the moment so that will just have to wait.

If you can afford Ultegra - then you can also afford the entry level Campagnolo, either 10speed veloce or 10speed centaur - several stores have those groups on sale. In my personal opinion, both veloce and centaur are better than both Shimano ultegra or SRAM rival. Really, even the old Mirage is better than both ultegra and rival.
Best of luck
