And if you DETEST 105, you REALLY won't like the front-end shifting of a SRAM setup.

Hang it up. Go single-speed.

In all seriousness, the only thrill of a build-up (IMLTHO), is in the building itself. After a few months, it's just another bike. Even buying parts wholesale, unless it's a frameset you cannot obtain already built up, it makes no sense building up a bike (especially not financially).

Find a good bike that already retails with the components you like. Financially, it's a better/smarter deal.
