Just read your other thread. You might want to PM ridethecliche and ask about his experience. I see one poster in your other thread mentions flex, as well as a few in ridethecliche's thread, but as he writes in one of his posts, it doesn't seem a big problem.

A question: how tall are you? Could be this frame is too small, unless you like small frames. Looks like ridethe cliche likes small frames! That saddle to bar drop would kill me.
