Useful Grit Combinations

500 Abralon
This reaction causes the ball to read extremely early. This usually on works well on extremely heavy
patterns or very direct angles by speed dominate players.
360 / 1000 Abralon
This reaction gives the ball more length than 500 alone, but still has a significant ability to generate
friction in heavier oil. This works well on heavy patterns with fresh back-ends.
500 / 2000 Abralon
This reaction is a very good benchmark reaction as the ball has enough topography to still generate
friction in medium to light oil, but not enough to cause the ball to read too early in most cases. This
finish delays the hook transition, allowing for a strong entry angle.
500 / 4000 Abralon
This reaction works extremely well on multiple patterns, giving the ball easy length through the
heads, a subtle but noticeable mid-lane reaction, and an enormous amount of friction at the end of the pattern. This finish can generate some of the strongest entry angles possible on fresh patterns, but may start to skid too far as the pattern carries downlane.

The lowest grit should be applied with more pressure, but for a shorter duration. The higher grits should be applied with less pressure, but for a longer time. This will have the desired effect of creating strong surface deviations to displace oil, but will also round the edges, peaks, and valleys enough to get the desired amount of skid.

 

Mo Pinels Skip a Grit

Skip a grit is intended to end up with two alternating different depths of scratches.

Skipping a grit allows the ball to check harder at the breakpoint while still getting good skid in the front. When you want control and a smooth breakpoint, use the correct grit sequence. When you want to make sure the ball reads the breakpoint, skip a grit.

To do the "Skip A Grit" procedure: Sand 4 ways thoroughly with the first grit and sand two ways quickly with the second grit.

  • 360 / light 1000
  • 500 / light 2000
  • 1000 / light 4000
  • 2000 / white pad
