Rob - This has happened to me a couple times. One time I let it go and "wrassled" it every time I tuned it for a couple years, after which it surprisingly became very nice to tune; firm, but no wrestling match. The second time I actually turned the most objectionable pins back and forth MANY times by 1/4 turns and that was very helpful in that case. No guarantee, but worth shakin' a branch or two to see what falls out!
