Nate,
Before you decide, do a Google on Pat Tillman. He made a pretty good North star, I think. I just finished 30 years service, 22 of them in the reserves. My reserve experience got me my airline job, paid the bills between jobs, and gave me the option to not take any job because I had to. You get the privilege of serving your country, meet amazing people, and gain a lot of self-respect along with the gratitude of society for your service. I think it's a no-brainer.
Yours,
