Sculpting Brush Saving

I find the default smooth brush in sculpt too agressive.

Every time I open a new Blender session I have to adjust the strength from 0.7 to 0.2.

I could duplicate the brush and save a new one with the setting I want. But then I'd have 2 smooth brushes which I don't like. And you can't delete the original smooth brush.

Also, when holding shift while using another brush, the default smooth brush would be used. So it's pointless duplicating a new one.

I don't like this behaviour. Unless I'm missing a way to do this?
