I think Fred was a hunter and knew what he liked and made bows he would want to own. You don't see much by way of wild, radical or extreme in performance or design elements. He made rugged, reliable and smooth hunting implements that could be counted on no matter what. That is why they endure. They are good. Damn good.
Ben Pearson was a hunter who designed a bow manufacturing process, and the end result is similar. A range of conservative bows that could be repeated in a manufacturing setting and be smooth and reliable.
You don't see a good day/bad day bow from either (while they were alive and in charge). They were all good day bows.
