It's not resins that are the problem nor are particles necessarily the solution. As is the most common sensical approach, you need more ball surface at the backend or you need to move more to the outside, depending ont he degree of carrydown, IF CARRYDOWN IS THE PROBLEM.
Most, but not all particle ball, SEEM to have more surface or a more grippy surface, but again, that is not alwyas the case.
In the most simplistic solution, you may simply need to add a little surface to the ball you are currently using (via any of several different ways: sandpaper, trizact, or a sanding liquid, like Neo-Tac's Hook-it or Liquid Sandpaper) or use a ball with more flare at the backend, like many of Morich's ball's do.
There are several varieties of this solution.
