supalite mono and flocked!both very light good brushes.(the issues with the mono bristles have been rectified)they also have a reinforced bit(the bit you screw your angle adaptor into).
vikans are good brushes but are too heavy to use day in/day out on your main pole
if your planning to work every day in this game you need the lightest gear to minimise strain and injury IMO
