I can second that, my first whisperstik was purchased from somebody else here. And JD was very accommodating on all my questions, and got back to me promptly with either e-mail or PM.
And it was because of that, I purchased my second whisperstik And JD got back to me promptly, I am looking forward to reporting on that one. He makes a very fine quality bow, no hand shock, and super quiet, and I might add, very accurate. He could give me problems. That would be a third bow, and that would be a good problem !
