Gregg has black leather for the grip, and I am sure he could put whale balleen on the tips and riser if you provide it. I have several Shrews, including the right-handed twin of Eric Westbrook's bow as a result of Gregg missing the weight on Eric's bow and realizing it before having to make the bow left-handed. I even got it at a point where Gregg could add a Bow Bolt. A Shrew Gold is a beautiful bow. I like the black phenolic with the golden osage in the riser and refer to that combination as a Bumblebee Shrew, for obvious reasons. There are many beautiful combinations, and I have a few of them. One of my favorites is a dark bow that has a Texas ebony and black phenolic riser with macasser ebony limb veneers. It and the Bumblebee are my two most striking Shrews, but I am working on ideas for the two I have on order.
