We are all different and there is a reason seatposts and stems are adjustable.
My bikes have drops in the 3-5" range. That's what works for me.
For those who advocate substantially higher stems, remember that part of fit and riding performance is weight distribution. The higher the stem, the more weight on your butt.
Now, what I don't get are the pics of bikes I see with the stem substantially above the seat and Brooks saddles pointing up towards the sky. Literally, I doubt I could ride a bike set up that way.
BTW, each and everyone of you should devote a 10 minutes everyday to progressive stretching. It will do wonders for all of those sore backs and necks you complain about.
