I run them on my Salsa Vaya Travel, partly because it splits and it’s less faff if I have to whip the bars and stem off and partly as it’s easier to replace cables damaged touring or during transit.
I love the feel of it personally. With just a guide on the BB and the rear cable loop from stay to mech, there’s hardly cable or any drag or outer compression. It feels so direct.\
It’s also nice being able to feel what gear you are in from the lever position. Overall a much more tactile experience than using conventional brifters.
Standing to attack and shifting gears is not something I’ve managed comfortably, but its hardly an issue touring. And when the Strava mamils want to play racing, I just counter their efforts seated.
Oh yeah, I run DA and they look loverly and make the crispest and most satisfying click on gear selection.
