You're just a bit shorter than me. I reckon the Sprint will feel pretty cramped, also the more 'head down, arse up' riding position really isn't so good for filtering.
The Crossrunner and Crosstourer are nice bikes, or why not move up to the big Varadero? All very competent bikes, the Vara and the Crosstourer will not only handle the commuting, they'll also carry you effortlessly across continents. In far more comfort than the more sports oriented bikes can....
But yeah, get through your test, then take your time and get lots of test rides
