Betsy - I think it sounds good as long as they are refutable clinics. Cons that I can think of: since they would be doing pro-bono it would probably (maybe not) be totally on their schedule, so they might be hard to work with as far as your and Carlos's schedules. Clinical trials are usually pretty safe though, I think, because they've already done lots of tests in the lab and on critters . I hope you find some good info.
