Asymmetrical neck profile.

[BigSteve22]

I'm glad I'm not the only one who's extremely picky about nut width, not to mention back shape. I agree, 1/16" feels hugely different! Although to put it into context, the limits of size differences that human hands can feel in general are really crazy small:

Thanks for posting those links, explains a lot. If, as the first article states, you can feel a difference of 9 microns, consider that 1/16" is equal to 1587.5 microns! That may be at your finger tips, but it says a lot about sensitivity....  :headbang:

When our hands clench, they do not close with a symmetrical shape. Therefore, asymmetrical neck profiles are worth giving a shot.

I am fond of the Wolfgang profile myself, but that's only because I have not had the luxury to try all of the neck shapes. (Loaner necks, anyone?)
