I was aware of the formula considering displacement, beam, length, engine, and a few additional factors. The key, as you suggested is to locate a "good" prop shop. After talking to several prop (local & national) folks who seemed to be afraid of this change I found Bill Jennings at Ace Propeller out in Washington who tackled the task head-on. Long story short, I got the new prop on this weekend, and hopefully will be testing it in less than a week. Will let you know how it performs.
