If your pain starts up again I'd suggest switching to something like a V1.
Intersting observation. Did you feel pain in your hand or your wrist or your arm? I probably played about 40 hours total with it strung full gut this winter and never experienced anything but pillow softness. I found myself swinging a little slower which gave me more control and I perhaps rarely missed the (huge) sweetspot. I will pay attention to this when I hit next with the new strings. Thanks.
