I am now.
Holland, I'm going with DA9000. I've only ridden Shimano, and unlike the haters hiding out in this thread, I like it. I was going to go Di2, but that's really over the top for where I ride and the type of rider I am, and though I could justify dropping 9 grand-ish on a bike, all things included, it's funny how I couldn't justify going just that bit more. If I'm still able to ride as I do now in five/six years, I'll get another bike, and maybe go electronic.
Last day of work before vacation....new bike arriving tomorrow....if I can get through today, life is good.
