I have had some dealings with Arthur Hatfield. He is a top notch guy. He only builds Bluegrass banjos though. Your buddy Hugh has a few of his bridges on his 'jos. Talk to him about Arthur.
The price difference between it and the Louzee would allow you to buy an open back for Clawhammer. They are two different animals.
I have also heard good things about the Louzee, but they are a lot more expensive.
