Pretty much me too. I've fairly tall (6' 1.5"), but have a short cycling inseam and a very long torso/arms. I actually settled on a -17* stem and it works pretty well for longer rides, but I've also gone to a bar with a touch more drop. So I think it evens out.

I've ran my stems slammed, with no spacers below for years... I don't think that's a real issue.
