JMO..but both your balls are pin down meaning early roll and ball with that amount of flare can not cover a large amount of boards across the lane without burning out.   You can play a tighter line with a lot of speed but I just think both these balls are drilled too strong for the conditions you're bowling on.

IMO....the IS is a condition specific ball as will be the New Breed Solid.  Most of us just don't see that amount of oil.   See Stephen's reviews on the NBS.

I just think that is why most of us will be using balls like the New Breed Pearl like many used the Immortal Pearl rather than the Solid.  

For more info. see what I did last week in the Good Scores topic on this forum.  I played a tight line with a weaker drilled IS and scored well.

If I was too drill another IS for my stats.  I'd drill it pin over ring about 4.75" pin to PAP and CG stacked straight down about a 90 deg. layout.  For me it would get some decent length with enough recovery but no early roll or burn.  Why I'd lay out this way would be for some strength left too long a pin to PAP would not give enough recovery for a tweener or fluffer. Pin down would read too early for most lane conditions and most players.  

Like I said the IS is condition specific....I believe too many people are using the IS laid out wrong for the wrong condition but that's just me.

Synthetic with what lane condition on them?  What type of synthetic?  How old?  What do you score with when the IS won't work?  Trajectory? Your stats?
