Just to note, I am applying to Ortho, but I had a female friend ask me about OMS.
OMFSCardsFan, you are probably a cool guy, and I've heard the exact advice you're giving many times before. Maybe it works for Oral Surgery where you will be in the training for 6 years, so it's important to find someone who will be able to tough it out for that long and be sensible. However, when I've been to ortho programs to visit or interview, I've found myself meeting many residents and thinking "man, this guy really fooled the interviewers on interview day. He's a total prick/tool/real bore."
Maybe it's different for ortho since the residency is much shorter, 2 to 3 years. But I don't know about having an opinion, I was told my opinion was wrong at one interview. Basically, the interviewer was harrasing me about the places I had applied and why I wouldn't want to apply to the top dog programs and get the best ortho education possible b/c he was a grad of a top dog program himself. I very nicely said something to the effect of my stats, whie competitive, would probably be thrown out at a top dog program. Seeing as it was my second time applying to ortho and my first time had included several top programs where I got zero interviews, I didn't think I was wrong the second time to approach programs where I would have a better chance. Long story short, I got a huffy response about why my approach wasn't the best way to get the best education, blah blah blah. I really didn't know what to say after that, I felt like I had been shot down big time.
Lesson learned for round 3 of ortho applications: Maybe it's good to have your own opinion, just make sure it's the opinion that agrees with the interviewer.
