I tend to focus on flex as that's a major issue for me. I haven't
studied the molds. I think that there are complaints about the
differences between Pro Stock and Retail frames and one of the large
factors is stiffness. Frame size, string pattern, etc. are also
factors that are discussed but I think that the difference between 98
and 100 square inches is minor.
Other major factors are static and swingweight. Clearly the finished
Pro Stocks and Retail frames usually diverge a lot. I don't think that
there's much you can do about this.

Thanks for putting a number on it. I'm glad that I didn't pick one
up - at least for hitting.
