Funny you should mention this...

My brother went to Tulane and did their MBA/JD joint degree program. He's been part of the working world for... maybe eight years now. If I remember right he was there for five years, maybe six. He did his undergrad in marketing at SF State. He's barred in Louisiana and as of three years ago, Texas. He deals with oil/gas/minerals and travels to China/Taiwan a few times a year. He travels from LA to TX a lot, for a few days at a time. He doesn't litigate though, I guess the company he works for retains "real" lawyers for that. He just negotiates, drafts letters and manages a team of lower level negotiators. From what he's said he apparently he relies more on the MBA portion of his education (managing, projecting etc) than on the JD.

If it's something you're seriously interested I can pass along any specific questions you have about the Tulane program you have to him, or put you in contact with him.

If it's between the two, I'd go with Tulane for the reasons people have already listed.
