You have my vote for president of the DT Shifter Club!
I love the 105 shifters on my Portland but, I find myself shifting perhaps too much.
With DT shifters, you have to put some thought into which gear you want to be in and stay in it longer.
You tend to look further down the road. And, once you get used to them, you reach down without even looking anymore. I have indexed DT shifters on my '95 Le Tour and that RD just snaps into gear in a split second, up or down. It's all about the cable tension isn't it?
