If you're trying to stretch a 3-season tent to cover winter in the Midwest (I'm from Ohio, so I do that, too), you might consider the MSR Hubba Hubba instead of the Carbon Reflex (aka Hubbless) tent.

The CR2 is MSR's first outing with carbon fiber poles; if I were expecting a significant snow load (and your snow is significantly more than Ohio's, I think), I'm not sure I'd be ready to trust carbon fiber. The HH poles are aluminum (and the tent is a little heavier - and sturdier? - as a result.) I'm not knocking the CR2 - I've used the CR1 in 3-season conditions, and really like it. Also, I don't do much snow camping anymore and have no experience with carbon fiber in cold, snowy weather (maybe some of you Tarptent users, or mountain wanderers, might chime in here?) But I think it's something you want to check out before you finalize a 4-season decision in favor of the CR2.
