Do any of your T1s offer some kind of LRAP program?
Wake is not a national school, so if you aren't sure you want to practice in NC or one of the surrounding states, don't go there.
If you truly are committed to working in a lower paying public interest job, you need to take a serious look at your finances and decide if it is worth it for you. The better school may help you get a job post - grad, but you will have serious debt to deal with. Keep in mind many public interest employers do not hire until after you have passed the bar, i.e. until several months after graduation.
One thing to keep in mind is the College Cost Reduction Act passed by Congress. This is supposed to help law students in debt who are working in public service jobs but the regulations that detail how exactly it will work are not out yet.
If you change your mind about public interest and decide to work in the private sector, keep in mind you'll have to make a decision soon. Recruiting for many large and mid size law firms will take place as soon as you arrive at your new school.
