Thanks again gentlemen. I’ll be seeing the rheumatologist next week and have restarted taking 1500mg of Glucosamine per day.
One “hardware” idea is perhaps switching to a recurve with a heavy riser to cut down on vibration. Another possible solution came to mind when I was looking at the photo in 3Rivers Archery of a Great Plains one piece recurve. The back of the grip is quite flat with what “appears” to be noticeable corners. My first thought was, "Boy, I bet that would hurt" since I grip with the thumb and all my fingers when shooting. But...if I shot a recurve with a grip designed to be shot with an open hand, then the only fingers that would be in contact with the grip would be the thumb and forefinger. In that case then the little and ring finger (the ones currently affected by arthritis) would not experience any vibration upon release. Hmm…
The down side is that it could be tough to make that transition after shooting 50+ years with a full grip. - Kent
