Does your LBS have a bike fitting machine that they can set up for you? One of our LBS has this "bike" that they can change to whatever the geometry you need based on the spec of the bike you're looking into. DH bought a Linksey from them because they were able to pull all the data off the web, set the geometry of this bike for DH to try out before ordering. Sorry. I know there's a technical term for this "bike". Maybe someone here knows what I'm talking about?
