The diff of the ball and the layout are what cause track flare.TomaHawk wrote: Just for sake of visualization, a low rev player would essentially rotate the sponge two revolutions. Each of the two revolutions comes in contact with a different part of the sponge. Compare that to a bowler who can rotate the sponge six times, each revolution comes in contact with a different part of the sponge. To state the obvious, the more times the sponge rotates on a fresh part of the sponge, the higher the potential for removing oil from the surface.
That is a simplistic explanation. Hope it helps though.
I am a very low rev bowler, but on my Widow Urethane ball and my Crow Urethane, both of which have high flare layouts on high diff cores, I am getting between 5 and 6 lines of flare.
I imagine a high rev bowler would get higher than 6 lines more closely spaced, maybe double that amount.
If the USBC is afraid of lane breakdown and oil depletion, then limit the diffs on balls so they do not flare much, even for high rev bowlers.
