Lunatic Series


Please Note: Because all bowlers have different positive axis points (PAP) your layouts may not have the same appearance as the illustrations. Also the layouts are for right-handed players. Remember to flip or rotate to produce "mirror-image" for left-handed players.

900 Global Drilling Layouts

  • Step 1. Identify your Bowling style. In order to accurately determine a drilling pattern and final ball surface, you must first identify your personal bowling characteristics; these three key factors must be determined.
  • 1. Bowlers Ball Speed
  • 2. Bowler Rev Rate
  • 3. Bowlers Axis Angle of Rotation
  • Chose the number below in each category that best describes your bowling style.
  • Step 1:
  • Ball Speed 1 = slower, 2 = average, 3 = faster
  • Ball rev Rate (RMPs) 1 = cranker (18 or more), 2 = tweener (13-17), 3 = stroker (12 or less)
  • Axis angle Rotation (side roll) select from one, two, or three
  • Step 2: Total your numbers up from ball speed, rev rate, and axis rotation. Use that number to select your drilling pattern.
  • Step 3: Layout must be based on your Positive Axis Point, illustrations are all based off a 5-1/2 over PAP.
  • Step 3: Choose your lane condition.
  • Step 4: Adjust surface.

  • Produces less flare for increased stability and control!
  • Creates less entry angle and a more predictable ball path
  • Works well on 'Wet/Dry' both front-to-back side-to-side - lane conditions
  • Good for Higher Rev Players

Master Drilling

Note: For reaction adjustments, consult the Ball Surface Reaction Guide. 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 1

Storm Master Drilling Layout 1
  • With this layout, we place the pin 5-Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?¾" from the PAP, above the finger holes, to produce length on drier conditions.
  • Next we select a mass bias, MCÃ?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?², position suitable for our desired breakpoint shape.
  • (A) Mass Bias in the ball track - designed to prodce 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 PAL - produces the earliest breakpoint of the three positions while providing a controllable and "readable" backend. - Works great on heavy oil patterns!

Layout 2

Storm Master Drilling Layout 2
  • With this layout, we place the pin 4-Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?¼" 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 MCÃ?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?² position:
  • (A) Locate the Mass Bias halfway between the ball track and PAL - designed to produce a sharp breakpoint
  • (B) Place the Mass Bias at the PAL for an easier, smoother, breakpoint.
  • (C) Place the Mass Bias 2" past the PAL for a very heavy midlane roll on long oil patterns.

Layout 3

Strom Master Drilling Layout 3
  • With this layout, select a ball with a pin 3 - 4Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?½" out from the CG.
  • Place the pin 2Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?¼" from the PAP.
  • Locate the MCÃ?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?² on the players ball track.
  • Weigh the ball to ensure static balance is withing 1oz in both left/right and finger/thumb directions. For this particular layout we will not use a balance hole.
  • This layout will produce an early roll, a minimum amount of flare and works well for controlling conditions with dry backends.

Layout 4 - For Full Rollers

Storm Master Drilling Layout 4
  • For players who track between the fingers and thumb (full rollers), place the major pin 4-Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?½" from the grip center in the southwest direction.
  • If a weight hole is necessary, be sure to locate it 6 Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?¾ from the grip center in the direction of either the major pin or MCÃ?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?² pin.

Basic Drilling Instructions

Storm Basic Drilling Lengend

Layout 1 - Label Drilling

Storm Basic Drilling Layout 1
  • This layout is considered to be a standard "Label" drill and will produce good length with mild backend reaction.
  • Place the center of gravity so as to balance Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?½ oz. positive and finger.
  • Rotate ball so that the pin (if applicable) is located at 1:30 in relationship to the center of gravity.
  • This layout will require no balance hole.

Layout 2 - Leverage Drilling

Storm Basic Drilling Layout 2
  • This drill pattern is known as a "leverage" drilling. This drilling provides medium length and maximum backend reaction.
  • In this layout we place both the pin and center of gravity 3-3/8" from the positive axis point.
  • Most often this drill pattern will require a balance hole to remove excess side weight.
  • Place the balance hole on the PAP and remove excess side weight down to Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?Ã?¯Ã?â??Ã?¿Ã?â??Ã?½Ã?Æ?�Ã?¯Ã?¿Ã?½Ã?Æ?�Ã?â??Ã?½ ounce positive.

Layout 3 - Axis Weight Drilling

Note: Be sure to select a ball with less than three ounces of top weight!
Storm Basic Drilling Layout 3
  • This drilling is referred to as "axis" weight. It provides early roll with a smooth, controllable backend.
  • Place the center of gravity on the player's positive axis point.
  • Rotate the ball so that the pin is located on the line between the PAP and finger holes.
  • Place the balance hole on the PAP and remove excess side weight to less than one ounce, This will ensure the balance of the ball is withing USBC specifications.

Lane #1 Drilling Instructions

  • Positive side, finger, & top weight increase length and back-end reaction.
  • Negative side, thumb, and bottom weight decrease length and back-end reaction.
  • Axis holes decrease flare and back-end reaction.
  • Pins closer in and under fingers decrease length.
  • Pin-outs 3+" and over the fingers increase the length and flip.
  • If ending center of gravity is on your pin, CG or on the same rotational plane as those, reaction is enhanced.
