what is your favorite/best spotting brush?

It would help if I new wjhat a "spotter brush" was..   I know flats, rounds, and fans, but never heard of a spotter..

 That said, I use Grumbacher and Artist's Touch red and white sable rounds and flats, and my points are from 2 to 00... I don't bother with 00 to 0000000-types because they hold so little paint they're almost useless, unless you need to paint like one eyebrow on 1/48 scale figure..

I also use the Testor's brushes, which are fairly good.. 

Guess I should have said spotter, rather than spotting.

I use a toothpick, the double ended round type. I shake the bottle and take the cap off and stick it on workbench upside down. I dip the end of the toothpick in the paint residue in the  cap. Just enough seems to stick there to put the proper amount on the toothpick. Touching the end of the toothpick to the model them makes a dot about 1/32 inch diameter. You can drag it a little way to make a thin line, but you have to keep re-dipping to make a very long line, so it is best for making dots, like dzus fasteners, screw heads, etc. It is amazing how uniform the spots are with this method.  You have to redip for every dot.

Ok, gotcha.. Thans for the link.. Never knew that those were called "spotters".. Persoanlly, that one is too small, at 000... I'd use a "0" or even a "1" so that the brush would hold some paint, unless I was doing something like Don'stalking about, then I too would use a toothpick..

Tried the toothpick to paint an oxygen hose and some seat belts.  Worked very nicely!  It was easy to control the amount of paint on the pick also.  Very good idea.  

Thanks!
