About the scaling on the neck...
Distortion seems to happen if you use the individual parameter dials above a certain setting.
But if you use the main dial you can use a fairly high setting.

Toe curl...
I have noticed with some of my family when they are barefoot that even when they stretch their toes upward, the toes look like that.
My daughter, my sister for instance.
Others in the family, their toes look smooth on bending straight or stretching.
Guess it's just one of those things. lol.

Let me introduce you to my multiple personalities. :)
