No wonder you've been asking so many questions lately! It completely slipped my mind (though I know I read it somewhere) that you're a recent diagnosis. I've done the dual-clinic gig. As long as you don't have any insuarance hangups, checking them both out, at least at first, will be a good idea. As to the non-classical issues...well, I happen to think that ALL adult CFers have non-classical issues. As one of my respiratory therapists once put it "CF didn't read the book!"
Make sure you're going to a clinic that is accredited with the CF Foundation, and that they have a big enough staff to suit your needs. I was really fortunate at one point in my life to be at a clinic that had a nurse coordinator, GI doc, asthma specialist, endocrinologist, dietitian, and resp. therapist. These days I only have the CF specialist, the nurse coordinator and an respiratory therapist. It's a little more effort to get all my needs met, especially since there's only 1 CF doc at my clinic who sees over 100 patients.
I don't know what your insurance situation is like...that may make you a bit limited, but you'll figure it out <img src="i/expressions/face-icon-small-smile.gif" border="0">
Best of luck, and I hope you're able to get your questions answered. Remember, we're here for you if you feel overwhelmed with this dramatic new (in name at least) aspect of your life.
