I know what you mean about whats you "should" be running, versus what you end up running.
aT 6FT 4", I worry that my 19" Reign looks a bit small on me, but it rides ok and the smaller size makes it more manageable in the rough. Itll never been an XC machine, and a 21" gate would be a bit bizzare on a DH track.
My Surly Disk trucker feels best with a 70mm stem. Bike fits are an indication or starting place, but the ratio of our bone sizes varies, so can never be a hard and fast rule. I start with a textbook bike fit, then tweek.
