I wonder about something- For the guys who say that thin necks cramp their hands:
When you play on a neck that's comfortable for you, do you primarily keep your palm sort of "cupping" the neck, as opposed to planting your thumb on the back of the neck, and using it as your support?
Reason I'm asking, I primarily use my thumb, and as I age (I'm 61) it takes me a little time to get warmed up, and until I do, I get a little cramping in my palm area. I guess I'm wondering if it's a case of just not using that type of grip very often, and kinda like, if you don't use a certain muscle group, and suddenly start working it, you get some initial pain.
