Perspective Interview

For my interview I am debating between interviewing two different people. Their Names are Carlos and Patrick, both of them are personal trainers that I used to work with at OneLife Fitness back home in Atlanta. I am torn between the two because with Carlos I am much better acquainted and therefore I feel as if I could have a lengthier and more conversational interview, but Patrick knows much more about steroid use and therefore would be an excellent source for the pros and cons of their use. Regardless of who I choose, some potential questions I plan on asking are; What is your personal opinion on Steroid use in the bodybuilding community/sports in general, and if you believe that the benefits of steroid use outweigh the risks?
