Skinning - Weight painting

To be honest, I never managed to make the "Paint weights" feature of the Skin modifier work properly. Until now.

I didn't grasp the concept behind it because the Painter brush thingy in 3DSmax always defaults at the wrong preset. In order for this feature to work, you need to set the pressure very low, like 0.01. If you fail to do so, and leave it at default 1.0, it gets out of wack extremely quickly, making any adjustment literally impossible. Radius, on the contrary, seems to have little effect on the general behaviour, it just covers more of the polygonal area. 

Thinking about it, it must be because I use 3DSmax with a Wacom, which, in my experience, is not common between 3D artists. Pen pressure combined with default settings in painter give us unpredictable results...just a word of advise!
