mrmoofo - Our bikes are designed to have plenty of seatpost sticking out. Keeps the top tube out of the way. If you're happy and comfy on your large Soul, then get a large Solaris. They're 10mm longer reach, so you may need a slightly shorter stem, and you'll almost certainly need flat bars instead of risers. Do those things and the fit will be almost identical to your Soul. If you feel a bit cramped on your Soul, get the XL. I'm 6ft 3in and have been perfectly happy riding both, but my personal bike is a large as that's my preference.
dlr - Not in the plan to do orange again. They sold really, really slowly on the Solaris for some odd reason, but the green we can barely keep in stock. Might do orange instead of blue at some point.
