I would wager that while you're a bit taller (I'm just over 6' and ALL legs), we probably ride about the same size bikes. For reference, I'm throwing in a couple of pics of my 23" Schwinn High Plains set up to to tour/commute. It took me awhile to find the "right bike" in the right size to build a drop-bar touring MTB, but the HP has worked pretty darn well.

There is a fair bit of seat post showing, even with the XXL 23" frame, but the high rise stem (atcually a stock stem) makes up for it. The top tube is a bit longer at around 24". I think I would have preferred to find a Trek or Diamondback as they seem to generally have more braze-ons and eyelets, but the HP has done fine for me on mixed surface long distance rides.
