I have been using the older XT dual controls for 2 years now.
I find them totally intuitive now,with changes just a finger flick or pull away,and my thumbs can stay round the bars,plus they have a very light lever action.I junked the thumb shift as I never used it.
Use them with a rapid rise rear mech ideally,then its flick down to change up,flick up to change down.
Both left and right hands and shifters then move the same direction for up and down shifts.
Lots of people coming from rapid fire ,slate them without having allowed themselves to get accustomed to them.
I was told that I
b
t be able to do endos, the levers would break,etc,but my experince has been positive.
Only negative for me is not being able to mix and match brakes,and I`d sometimes prefer something with a bit more bite and lighter than my XTs
