For that matter, does anyone know for sure if the real deal is a particle coverstock or not?
dpunky - While particles are typically/generally better in heavy oil than non-particles, the ball companies are doing a good job lately producing strong reactive solids (non-particles) designed to handle heavy oil. However, my opinion is that particle coverstocks do not last as long - that is to say, they weaken from their original strength more quickly - as the non-particles, so there is that to consider as well.
In all, with the correct layout, either ball will likely work well for you.
