with Tribo, less is more... scratch the face of the brush with an xacto in order for Tribo to soak in, then put a drop or two on the face, keep it vertical for 15minutes, et voila, 15 minutes after the tribo's gone in the brush, you can break them in... that's pretty much all you need.
After lots of packs... I have noticed no performance gain using tribo, no matter what BJ says. BUT it does help a LOT with comm wear and brush lifespan... I can use Quasar brushes for more than 20 runs with Tribo (that's on 12T, we're in Europe here
). And the comm suffers a lot less and requires fewer cuts.
Once again... with comm drops in general, less is more...
