Layout 1

Storm Master Drilling Diagram 1
  • With this layout, we place the pin 5-3/4" from the PAP, above the finger holes, to produce length on drier conditions
  • Next we select a mass bias, MC2, position suitable for our desired breakpoint shape. (A) Mass Bias in the Ball Track - designed to produce a late and smooth breakpoint. (B) Mass Bias in the Strong Position - this will produce an earlier and sharper breakpoint than Position A. - Good for extreme entry angle! (C) Mass Bias on the Perpendicular Axis Line (PAL) - produces the earliest breakpoint of the three positions while providing a controllable and "readable" backend. - Works great on heavy oil patterns!
  • Be sure to check for excess side weight and finger/thumb weight, as a balance hole may be necessary for any of these layouts. If one is required, draw a line from the center of the grip through the CG and extend to the PAL. This will be the location of the balance hole.


  • Layout 2

  • With this layout, we place the pin 4-1/4" from the PAP. This position will produce medium to high flare, great for players trying to “open up" on a medium to heavy oil lane condition.
  • For bowlers with medium to high rev rates, this in position will often produce the most overall hook throughout the entire lane!
  • Now select an MC2 position: (A) Locate the MC2 halfway between the ball track and PAL to produce a sharp breakpoint (B) Place the MC2 at the PAL for an earlier, smoother breakpoint. (C) Place the MC2 2" past the PAL for a very heavy midlane roll on long oil patterns.
  • Be sure to check for excess side weight and finger/thumb weight, as a balance hole may be necessary for any of these layouts. If one is required, draw a line from the center of the grip through the CG and extend to the PAL. This will be the location of the balance hole.


  • Layout 3

  • With this layout, select a ball with the pin 3 - 4-1/2" out from the CG
  • Place the pin 2-1/4" from the PAP.
  • Locate the MC2 in the player’s ball track.
  • Weigh the ball the ensure static balance is within 1oz in both left/right and finger/thumb directions. For this particular layout we will not use a balance hole.


  • Layout 4

    FOR FULL ROLLERS

  • For players who track between the fingers and thumb (full rollers), place the major pin 4-1/2" from the grip center in the southwest direction.
  • If a weight hole is necessary, be sure to locate it 6-3/4" from the grip center in the direction of either the major pin or MC2 pin.
