Hi Julian, I want to encourage you to try this handle style. Might turn out nice!
Even though glossy and shiny is pleasing to the eye (and dents and scratches can lead to a bow breaking), a part of me cant stand it too pretty, replicating the look of fiber glass and plastic era bows with perfect surface. I feel similar about neat leather sewn on handles to be honest. Too much victorian era -robin hood romanticism for me:) Leather or suede soaks up moisture and transports it into the bow. I prefer it a bit rustic. I like to bring the character of the wood out with a nice finish and I tend to leave the grip bare, or wrap it in cord or simple strips of leather I can remove if wet.
