Ric,
You are also making the major assumption that particles are only for use in heavy oil to help a ball to hook. That has not been true for a long time now. There have been many balls that have used particles, for much less than heavy oil, just to give you a different look and feel in the ball reaction.
The major use for particles other than for handling true heavy oil has been in the area of polished and matte finished pearlized particle. Balls, like the Storm Shift and the current Lanemasters Buzz Attack and Black Pearl, are there to give different looks for medium to medium-heavy oil lanes. Lanemaster future ball, the Xtreme Damage, will also be a particle pearl.
Roto-Grip even put a 1% load of particles on the medium-light oil ball, the Venus.
As for your true solid heavy oil particle ball, you also left out the 900Global Bounty Hunter, which has 3% load of particles. The Storm 2nd Dimension uses Mica, like the Track 930T, but is a polished pearl resin, using large particles of mica to help prevent it fom skidding too far.
