I'm wondering what layouts tend to work for you guys, and what type of layouts(if any specific ones) typically give a good reaction on sport patterns.  What type of reaction is that for you?

My thinking is that very controllable reactions are typical for sport patterns, not exactly a true arc but definitely not skid/snap.  That would help avoid over/under right?  Then there's the question of the ball having enough energy/entry angle to carry.  I'm wondering how one would acheive a reaction like that through layouts.

My stats are in my profile.  I prefer to play straighter but most times it seems like that type of line just isn't there for me unless I don't come around the ball as much.  That could be just because the PBA patterns I've been bowling on at a particular house is hooking a little more than it should be.

cheech, I also have a Rival, it's drilled 4 1/4" x 4" pin under ring.  I leave it at 2000 abralon.  It's one of the better balls I've thrown for sure but I still run into over/under problems more often than not.  I get a good midlane read and a hard arc out of this ball.  For what it's worth, it flares about 2"(maybe a little more) I think for me with about 1/8" separation between the oil rings.  This is next to the space between the fingers/thumb, not sure if that's the location you're supposed to measure the flare at.

I'm not saying I'm perfect but I do expect a little area even on sport patterns.  Not sure if I should use weaker drillings, stronger drillings, more surface, etc.  Again, the problem is not hook but just over/under, missing in a pinch results in hitting the face and missing out a board or two results in washouts or 2-8 variants.  Sometimes it could be lane play which is my fault because one time I just moved in 10 boards and the pocket opened up, I had 3-4 boards at the breakpoint to strike and the worst thing I left playing there was weak 10s. This was on the Chameleon.

It sounds like around 5" pin to PAP for you is a good controllable reaction, in general.  Being a little rev dominant, even with not so many revs you'd think that would work for me too.
