Try taking the ball down to 500 grit abralon then hit it with either 2000 grit or 4000 grit.
The underlying surface might be too smooth causing you to move deeper than you really should be on the lane creating the flat corner pin dilemma.

The Favorite was a beast for the 1st 20-30 games or so until it glazed up for me.
I still keep one in the bag for burned up conditions.

My other thought is what kind of layout do you have on it and what kind of lane surface you bowling on.

sounds like the same layout that i used, and i had similar results ,i wasnt real fond of the ball till i hit it with some black magic polish  wow  what a difference that made, it reads the lane better  and hits twice as hard,
now i just throw it toward the dry and it comes screaming back   
deffantely a better ball shined
just my two cents here
