What's your Ai technique for drawing stroke-less illustrations with the pen tablet?

I either make closed shapes with the pen tool then fill them with no strokes. Or, for stroked illustrations, I make the entire line-art (mostly with the wacom tablet) then do the whole "expand appearance, merge, paint a duplicated layer with the paint bucket tool" process.

But is there a way to create 'stroke-less' illustrations with the help of the pen tablet?
