MoRich Bowling Ball Drilling

There is no straight forward answer to this question. However, we have developed a highly technical algorithm that can pin point the best drilling layout for your game. In order to accomplish this feat, you will need to provide us with some rather technical information using the MoRich Drilling Request form. You may need to visit your Pro Shop operator to obtain some of the information (e.g.: spans, axis rotation, rev rate, oil pattern, etc.) to complete the form. This is also a good opportunity for your Pro Shop operator to see your game in action. Please note that any drilling recommendation is strictly for MoRich equipment as the algorithm utilizes specific MoRich ball specifications.

Know how to find the mass bias? Using the deTerminator simplifies the effort and accurately locates that special spot! Does your pro shop owner have one to aid with accurately laying out your equipment?

And to further your knowledge on the newest drilling techniques, take a look at the "DUAL ANGLE", "GRADIENT LINE BALANCE HOLE" and "DOUBLE THUMB" seminar papers, and the new Bowling This Month article, "Effective Layouts Developed by Modern Technology."

Sample DUAL ANGLE Layouts

*High Track Players (with PAP more than 5-¼" over)*
Desired Result	Drilling Angle	Pin to PAP	Angle to the VAL	Use	Recommended Pin Distance	Traditional PIN to PAP Distance	Traditional MB to PAP Distance	Traditional PIN to VAL Distance
Fast Revving - Firm Breakpoint	65°	3-⅜ in	25°	For most players on most conditions	2 to 5-½ in	3-⅜ in	5-⅝ in	1-¼ in
Strong Midlane - Heavy Forward Roll	50°	4 in	35°	Speed dominant players and/or for heavier oil volumes	2 to 5-½ in	4 in	4-⅝ in	2 in
Control - Smooth Continuous Hook	85°	4-½ in	45°	Rev dominant players and/or for lighter oil volumes	2 to 4 in	4-½ in	6-⅝ in	2-¾ in
Strong Backend	40°	4 in	20°
Late Breakpoint	85°	3 in	45°
