You only need a fitter if you're uneducated about fitting and/or don't own a large mirror or any equipment to make your own video. I've never had any major fit issues and never been to a fitter. There are so many good resources both in books and on the internet, that all you have to do is a little study to figure out the cure for most problems. I've posted links to several articles that are valuable.

I've never stated that setback and drop are interlinked, but with enough setback, you can tolerate more drop. Leaning further over won't place a heavy load on your hands, if you're back far enough.

I can't imagine how moving a saddle forward would ever solve hand and foot issues, but if you say so.

I changed my saddle to bar drop for no other reason than to see how it felt. The lower position should be more aerodynamic. That's why the pros use a lot of drop. I also use a low torso angle for climbing. Some people have lower back issues with a lot of drop, but I never have. It doesn't create any problem when riding with my hands in the hooks. I probably spend more time continually in the hooks than the average riders, since I do a lot of 10 mile mountain descents (4-5 times a week) and I'm in the hooks the whole time.
