Blender Brushes

[incolorinred]

What brushes do you use for blending (oil paints); size, shape, material?

I have been experimenting with a number trying to figure out what I like the best and what works the best. Would really like info from people. Thanks.

I can do a great deal of blending with a dry fresh hogs bristle filbert.
I also use ratty old watercolor sables - worn out ones.
I'll be using both at the Insomania workshop.
