Strider,
I am going to try to touch on every aspect of your message one at a time, and hope I do not end up missing anything.
I am the one that has said several times that it was suggested by Del W. and Mo Pinel while I was attending a clinic that the core was being better utilized when you kept the pin below the finger line. I had never really been able to do that with very many balls and not have my track clip my middle finger. With the Morpheous (or any variation of it) I have never had that problem, so I try to keep my pin below the finger line (be it below the bridge or drilled PIN 2 inches from PAP).
The normal "rules" still apply for weight holes. Atleast that is what I have always used when I have to add a weighthole to this kind of core. My rule, some pro shops do it, some do not, but I definately wait to see the ball used on the lanes before I apply the weighthole. Being able to use that as a tool to fine tune the ball for the bowler's desired reaction is something that should not be passed up.
I am not completely sure that placing the MB near your VAL is a good idea for the reaction you want to get out of the ball. When you place the MB near or on the VAL it makes the ball want to read the lanes sooner, getting into an early roll. I personally, and many of those I have drilled Animals for have had success with placing the MB in that position, but our games called for that kind of layout.
For alot of backend reaction and to have alot of recovery down the lane (after looking at your stats in your profile), I would suggest placing your pin 4in from PAP, which will place it near your ring finger. I would keep it just below your ring finger and I would put the MB about 1 1/2-2 inches right of your thumb. When you put the MB in this location you are getting it in a stronger position, but it should keep enough of the strength for the backend of the lane. Thus giving you the recovery you want.
NOW----with that entire paragraph said........if you have not tried a ball drilled with the MB your VAL.......do it with this ball. I believe that brings out the best characteristics of the core/cover combo and the general nature of the ball. IF you decide to do this, try the PIN in relatively the same position.
PLEASE do not be afraid to adjust the coverstock on this ball. You may be able to go with the MB on your VAL and add a light polish and still get that recovery (depending on the lane condition you are shooting on). If you want to use it on a little more oil do not be afraid to take that 1000grit compound finish off of it.
If you have any other questions, feel free to message me.
Goodluck
