Yeah, I moved to thumbies on my child/load carrying bike because DT shifters when loaded are horrible, I find. Obviously people have used them on tourers without issue but I found the combination of them with a very high load (child seat) made it all a bit too wobbly for my liking. I certainly wasn't able to spend the time making sure the shift was correct using friction; indexed shifters may be easier.
Been riding with Paul Thumbies+shimano bar ends for the last week; decided last night to remove the Thumbies and mount DTs instead. Aside from aesthetic hangups; I didn't like the reach required to shift into the highest cassette cogs, nor the force required to shift up into the large chainring.
Downtube shifters just hit all the marks for me; tactile indexed shifting [CLICK!], reliable due to mechanical simplicity, and they look elegant as fuck to boot! My only issue with them is the learning curve; but that's a skill like any other and just takes time.
I was however, concerned about mounting a front rack with DT shifters; not a fan of taking my hands off the bars when riding loaded for any reason.
