I think Dick Byron sold his handle business to Mike Stott if I remember right. To some they may be a little expensive, but, they are worth every penny when it will tame down an Old Timer that I could hardly get to fly level. I also think Brodak has a lower priced version of it. Also check out Control Line Central. DOC Holliday
PS: Forgot to mention Carl Shoupe and the Fancher Hard point handles.
