Dennis,
Its pretty simple with this bowling ball. I will admit to making the same mistake that most bowlers probably did with the original LINK and that is to drill it to be a big Skid/Flipper. Unfortunately, that is not what this ball is built to do.
Here are the specs for a 15lb Missing Link:
RG=2.560, DIFF=0.045, MB=0.006
The RG tells us that it will easily get through the front and middle of the lane.
The DIFF tells us that it will have a medium flare potential.
These two specs and seeing how tall the core is in this ball should tell the bowler/pro shop that unless there are extreme factors in the conditions, this ball is not going to be a BIG SWING ball. My definition of BIG SWING is playing something like 20 to 10 or 15 to 5. Now I know that physical games might be able to produce those kinds of angles (my hats off to you), but the majority of players can't do that.
So with that information, I believe it is important that 2 things occur when a bowler or pro shop technician puts a layout on this bowling ball:
1) Consider the conditions that the bowler is requesting this ball for and help them understand (like I hope I've done here) that this ball isn't meant to play big angles unless your physical game allows it. Most bowlers are going to get this ball as either Entry Level or to combat High Friction conditions.
2) When drilling this ball, my experience has been that because of the tall core, high RG value and medium DIFF, that it is important to throw caution to STACK layouts. I say this because as your PIN to PAP distances get longer (for me it was when my PIN to PAP layout came close to my PAP distance. ie layout=5" and my PAP=5 1/8"). What I saw from that was the ball got down the lane fine, but if it didn't catch friction it would wiggle.
What I did as you see in my review was to strengthen the pin by going a 1/2" shorter on my Pin to PAP distance and then I kicked the CG/MB out slightly to position the core so that it wouldn't be as sensitive to carry-down.
I hope this helps and its always good to talk to a ball rep, pro shop tech, or come on here to get a better understanding of the dynamics of the bowling ball or reaction you seek.
I do not recommend this ball if you are looking for a big backend reaction. Look at these balls in the 900 Global/AMF line for that type of reaction:
