MichaelH: good post, as Joel said. Good rundown of the pluses and minuses of each system.
I'd been using bar end shifters (friction) on my main bike for years and when I built up my Rambouillet I decided to go back to DT shifters (friction still) with a compact double (42/26... very compact!). I LOVE the DT shifters. What did it for me is the shifting with one hand technique that Michael mentions. When riding with DT shifters 20+ years ago I didn't know that trick, but it's so obvious once someone tells you or you figure it out. Makes double shifts (for me that usually means 1 in front, 2 in back at the same time) so easy and fast. I'm using the Campy FD that Michael mentions (that Riv sells -- I assume that's what MH refers to) and it's like butter. Doing the double (front/back simultaneous) shift is no more work than just shifting the rear. This is with the Silver shifters if that matters. One point of terminology and maybe this has changed since I last paid attention, but I thought SIS stood for "Shimano Index Shifting" (whereas Suntour has Accushift) and so it just means indexed shifting (which can be w/ DT, bar end, or integrated shifters). But maybe now SIS is synonymous with brifters. Ah well, who knows. At any rate, good stuff. There's really no substitute for trying out the different options and seeing what feels best. But also no penalty for sticking with what you know you already like!
