i used to drill everything with the pin at 1:30 and a little side weight.  I would just use a different ball to get a different reaction.  That was before I learned about how many options are available to fine tune ball reaction.  Some coverstock/core combinations work better with different drillings.  As for stacked leverage being the "strongest" drilling, I think you've been misled.  Stacked drilling provides the strongest backend reaction due to the maximum flare.  There are many drilling that I personally feel are "stronger" because they get the ball rolling earlier.  Also, max flare isn't always a good thing.  If I drilled a ball designed to get 7" of flare and stacked it, it would flare so much that the ball would eventually roll over a previous oil ring on the ball and defeat the purpose.  Then you throw in weight holes and surface adjustment to tweak the reaction.  Stacked leverage is the right drilling for many bowlers and many lane conditions, but the same could be said for putting the pin below the ring finger and kicking the cg out.  It is up to the professional driller to help the customer make the right decision based on there game and lane conditions.  Furthermore, most drillers will follow-up and make any adjustments needed, not just tell them to buy a stronger/weaker ball.

There are voices in my head that question my reasoning when drilling a new ball.
It's human nature to question ourselves.

The fact that BTM uses "Stacked Leverage for the Tweener's strong model" does make you wonder! I know it is a "Cookie Cutter" drilling layout solution that might and would have mass appeal and success. But remember it is only a "Strong Drilling Model" that they are trying to show. Notice that the Cranker and Stroker don't use the "Stacked Leverage" model, because they too are trying to optimise the results based on the bowler's criteria. I usually read between the lines here, and approximate between the Cranker and Tweener model to get an idea of a starting point for a customized drilling layout solution based on my release and reaction that I would like to see. (other words: Why I am buying this particular ball with the reaction based drilling layout that I'm choosing?)

... based on my PAP, Axis tilt, and Axis Rotation, and Professional Driller advice, the voice always says "NO Stacked Leverage drilling - will be too strong and you will regret it!"  

Well, you see I think most of us think we are much more wise about the "Reaction we think we want" then any proposed cookie cutter drilling.  In fact: I think most bowlers want a bet on their drilling hoping and praying for the reaction they want to see which tend to lead to strange and mathematical geometrical layout configurations.  (ie 4.25 X 2.75 65 degrees MB/ with weight hole to control spin time)

Secondly, this is an identity thing, a special drilling tailored for our own personal bowling style.  We want to feel some sort of control about the outcome of the drilling.  A guesstimate or estimate.  Which most times after seeing the reaction of the pin configuration think woulda, coulda, shoulda alternative drilling's.  Yeah, drill up another one of those, ball whore!

Out of 15 balls so far - I have only 3-4 regrets to admit.  But several were bandaged up with surface changes and weight holes. (which this board was of great service and help!) Hopeful educated experimentation is the price to satisfactory results.
