Here, try this site for Mr. Friedman: http://www.championkaratefl.com/index.html
It has quite a bit of information on him and his school. A few months ago I thought I was going to spend a week in Orlando, and asked an instructor from that general area if he could recommend someone to work out with, and Mr. Friedman was the one instructor that was suggested. I spoke with him over the phone for a few minutes, and he seemed very helpful and welcoming. I didn't get a chance to try his school out, but I would like to at some point.
My suggestion would be to visit both schools and talk with them, check out what they do, how they teach, all that stuff. Try a class or two with each. There are other threads with a lot of great suggestions about trying out new schools and choosing between schools, so I won't rehash all of that info. I just thought I would throw out what little info I had on one of the instructors you asked about. I don't know anything about the other one.
Good luck with your search,
Troy
