You're all talking about poly finished necks, what about oil & wax finish.... I found the oil & wax finished figured maple had the tendency to move a quite bit more. Had a Sterling with a crazy birds eye maple neck which needed weekly adjustment. And one of my 20th Ray's also was a bit on the touchy side. Coincidence?
I agree with Oli. My older highly figured necks do move a bit more, but nothing unbearable. I have a Stingray 5 with awesome birdseye that moves quite a bit, but a simple minor turn and it is back to normal. You cannot compare the finished necks of the 30th with the early oiled necks. Bottom line, I would not trade any of the early necks I have though.
