Flatbed LTL or intermodal??

I am about to get my Authority and have two brokers in mind. Both are solid companies that pay OK and on time and give much more freedom of schedual than any big freight company I ever looked into. I know I'll work harder running LTL on a flat bed, but the pay is a little better. I'm wondering what others think about doing that as compared to running for a inter-modal (container) transport co.? Both are within 40 miles of my home. Any words of wisdom?!
