Are you spinning out of your 50x11 in Illinois? I live in Colorado and can spin my 50x11 up to 50+ mph. I don't understand how a 52/36 is going to give you more power. All a 50t does is allow you to ride slower in the big ring before you need to shift to the small ring. If you're spinning out of a 50x11 in Illinois, either you have too low of a cadence, or you riding in the rare Illinois hurricane.
