Which are two no-no combo's unless you want significantly
(IME) excellerated chain and gear wear.
Having said that however, I get no cage/chain rub in
those combo's anyhow (XT rear mech, LX conventional pull
front mech).

I have never had a satisfactory set-up from an LBS, new
bike, or new tune up, which is why I do all the
tweaking myself.
It did take me quite some time to learn how best to set up a
front mech, though, and I find mine have always worked best
when I set the cage (via seat tube clamp) higher on the tube
than ****-man-no! recommend.
Trial and error, with some logical common sense, a good
eye, and a little foreknowledge, is a damned good
teacher, IMNSHO!
