I agree that some firms are, overall, nicer than others, but it is really hard to tell which is which. The LA firm that lets you wear jeans has, from what I hear, a lot of yellers. People focus on one aspect and draw way too many conclusions.
Dotlyn I'm in the same boat as you with the 167. That is encouraging information. I was practicing in the 169-174 range, with an average of 171, so hopefully I can improve at least a few points.
