Tough room.
Meteor2001, I would say that your chances of speaking to a "pro" is somewhat limited. What kind of "pro" were you looking for? Are you interested in soliciting expertise from a racing pro, a bike shop pro, a pro mechanic?
Regardless, I would suggest that you steer towards the rim style of brake. I say this mostly because you would more than likely know if you needed a speciality brake system (disk brakes.)
I love my disk brakes. I can justify their need for the type of riding I do. I also know their downside and I am willing to accomodate to those aspects.
