My tenor is an old (70's, apparently) and very worn-looking YTS23 and I love it, even without the top F#. Very solid, doesn't seem to mind what mpc you put on it etc. Great tenor, I used to have a Yani but I prefer this Yamaha.
It's been noted before that the Yamahas in general don't impose themselves on you, and so allow you to come out through your horn. I don't know if this is true or not as I'm not really that experienced (about 5 years in, self-taught) but it certainly works fine for what I want from a tenor.
