We have been working on making the bowling ball drilling layouts easier to obtain for bowling balls as we add them to our site.  Checkout the Brunswick Siege product page and look at the tab menu under drilling layouts.

As more information becomes available we will add it.  In the mean time you can see how this new section for bowling ball drilling layouts works.  We are working on getting a bowling ball reaction video done on the Brunswick Siege and should have it up in a week or two.
