What is the best strategy to get a master's degree as a KD Complete Army CPT?

I finished my KD requirements and am about 2 years away from my PZ look. I would like to start my masters degree now that things are more smooth sailing. What would you recommend and why? Advanced Civil Schooling is given out in far too few numbers in my branch and I believe that window has passed. I am looking at using TA or GI bill benefits to do it. What option would you recommend? I would must rather be a full time student if that was an option.
