To all:
It's looking like the Giant because of a deal I can work out.
I really like the Trek's proven performance and American heritage but the Giant ran just as sweet, it's lighter and the component group seems better.
Ah well, I guess I'll just have to buy a Fuel when I upgrade my MTB...
Thanks for all opinions--save the "pick the color of your eyes" one, as there are few brown bikes out there.
