OK.
First, don''''t really think of surface changes as changing the backend reaction, think of it as changing the length before the reaction occurs. The backend reaction is a product of the energy input Vs the energy stored. It will be altered, but by the amount of energy the ball retains at the breakpoint.
Yes, polish does tend to create length, but that is relative. There are many factors that relate to how a ball will react to surface changes, but here are some generalities that will get you started.
If you have a dull ball, then add polish, the ball should have more length and store energy better for helping the backend reaction.
If you have a polished ball, the dull it down, the ball should start earlier and burn energy faster on its trip down the lane.
You can adjust a balls reaction by using different grits on the surface PRIOR to polishing it. The FINER the grit, the more length you create and the more energy you store. The LARGER the grit, the less length you have and the more energy you burn, and the faster you burn it.
Now,
If you have two of the same balls, with the only difference one being pearl the other solid, the solid will tend to start just a bit sooner than the pearl due to the pearl additive changing the nature of the coverstock.
If you do the same changes to each ball, the difference between them will remain.
If you put the pearl ball at 500ab, then put the solid at 4000ab with high gloss polish, you will MOST LIKELY end up with an early rolling pearl and a skid/flip solid. In this case, the dull pearl would have more hook POTENTIAL than the polished solid.
