I need help picking out a new frame.

Here is the deal. I rode a mtn bike around Boston for 10 years (high school into adulthood). A few years ago I decided to get a more street orientated bike. I ended up with a Redline 925. I am now looking to start piecing together an upgrade over the next few months. I don't know much about bike geometry, but I do know that I wish the 925 had a little shorter wheelbase for more agile city / traffic handling. I also don't know much about long-term quality among the major manufactures. The frames I am currently considering are:

Pista
Iro Mark V
Kilo TT
Surly Steamroller

In looking at the specs of these, the geometry difference among them seems negligible. Yes, I am going to test ride before I drop money. That said, I am hoping some of ya'll could point me in the right direction as to these frames, and anything other ones I might consider looking into. Thanks in advance!
