I would not look at it that way.
For example, I was not a real fan of bending in the handle bows, until I received a sweet bow from Ken last year. Now, I not only like them, I am trying to build some.
I feel the trade idea is to make the bow you want to make. Who knows, you might get someone else thinking outside of their box. If you see a gull winged bow in the wood you are working, build it. I have all the confidence that the person getting it will be very happy.
