I had an FX 7.3 that I recently sold. I couldn't get it to fit right. That one and the Trek Lexa did not feel comfortable no matter how many adjustments were made. There was just something about the geometry of those two models that don't do it for me. I love my Trek mountain bike.
I also didn't like the disc brakes. They made crazy screeching sounds in the crosswinds. Everyday on the way home from work it was like having a herd of angry screaming squirrels riding with me.
The bike was smooth though, and pretty fast for a hybrid. I bought a Specialized Vita after I sold it.
