If I might digress, there is or was a saying in bowling,
"You buy a ball reaction, not a ball."
Regarding high load particles, there is not now nor has there ever been a need to buy a specific "load" of particles. This is like buying a car without looking at the engine but buying on the basis of the width of the tire.
You want traction and the load of particles in a ball's coverstock is only one way to get it. The gripping strength of most coverstocks are now much stronger than they used to be. So light or even null loads of particles might be stronger, that is, grippier than what heavy loads of particles used to be.
Again, this is like looking at the ONLY the ball's core's specifications to see what the ball's reaction is going to be.
As a final note: I can sand, polish and drill a high load Yeah Baby to give a flippy reaction close to that of many pearl resin balls. It is a hiogh load particle coverstock, that when sanded to around 1000 grit and drilled in an average manner can handle a lot of oil for a lot of bowlers.
