If so, whatever you do, don't get the later 10s with the hidden shift cables - finnicky PITA. Also requires a different RD to earlier 10s; the geometry differs slightly from (1st 10s)/9s/8s/7s/6s.
Better yet, get Ergos and a Shiftmate. The Shiftmate is a slight hassle but the Ergos pull more cable and thus index far more reliably... then there's the looks. A lot of folks are iffy about the newest shape, but the older one was available in 10s IIRC and can probably be found new here and there.
Shimergo is a sweet way to roll.
