Ok, I'm getting close to the "moment of truth".

Here are my options, based on what I have here at home to pick from:

1) New Dura Ace 9 speed STI
2) Almost new Ultegra 10 speed STI
3) well-used Dura Ace 8 speed bar-end shifters.

Which would you pick, and why. I like bar-ends, but I still prefer STI/Ergo/DoubleTap. Convince me....
