That's about the same touring geometry as my Gardin conversion (passed down to me), whose fit I've been perpetually battling over the past few years. My road bike fits me like a glove (a 55 cm virtual TT Lemond, which has fairly relaxed geometry for a road bike, but much more aggressive than a touring bike), but the 52 cm ST on the Gardin means that I have to have lots of seatpost extension to get high enough above the BB to avoid knee pain**. Due to the slack angles, this puts me even further back from the cockpit; so even with a 90mm stem, I end up feeling a bit too stretched out. This only became an issue when I switched to drop bars for a more comfortable commute, but I can't go back to flat bars.

Just something to keep in mind -- hopefully your fit will go better.

** To the point that some lycra warrior in High Park felt that he needed to tell me that I had too much seatpost showing -- I'm truly sorry that my comfort + proper fit doesn't match your "fistful of seatpost" aesthetic.
