Reed making for Concert D Brad Angus Chanters

Anybody successfully making thier own reeds for Concert D Brad Angus Chanter? I would love to PM message/email/skype or talk with you about material, process, and dimensions.

Brad makes great reeds and I have done a few that work well but it seems to be a narrow band of dimensions/ scraping where it does work. Other reedmakers ( that claim they can make a reed without having the chanter in hand), that I have tried, make reeds that do not work.

And I would love to share info with anybody who has been successful in making reeds for this chanter.

Thanks…
