The "Shrew Concept" ....short, light, quick, limb design...was Ron's baby ( I know, I know, there were short and light bows before Ron was born).
John built bows for Ron for quite awhile, and builds an excellent bow to this day. I have a McCullough Shrew and it is awesome. Guys love thier Griffins, for good reason.
My observation (believe it or not, Ron and I have never discussed this) is that Gregg and Ron work more closely together than Ron and John did. That is not meant as a negative comment at all.
But together, Ron and Gregg have built up some of the greatest "Shrew accomplishments"....the Li'l Favorite, the Classic, etc. These are GREAT days for Shrew buyers.
