I have a 15lb 4 oz Ambush that is drilled 3-3/8 inch from my PAP.  It is a 3 inch pin ball, the pin ends up directly under my ring finger and almost touching it.  I am a low rev player so I stay behind the ball, stand at about 3 board with right foot, and throw between 1st and 2nd arrows.  This ball is a killer after my heavy oil ball (Action goes away)  It is light load Particle with a little pearl mixed in, does not have a big backend. An arcing type of ball.  My pro drilled it this way so it would start up a little sooner on oil, but still have some length and handle carrydown conditions.

My feeling is if you drilled it up 2-1/2 inches from your PAP that it would start up too quick.  When lanes get too dry this thing will really hook, and I have to put it away.  That drilling might work on really heavy oil if you
don't have a lot of speed.  

I had a Columbia Detour with the exact same drilling 2-1/2 inches from PAP because the guy that drilled it screwed it up (not the guy I use now)  I grew to hate that ball because it started up way too soon and jumped when it hit dry.

ps I was just thinking that if you had it drilled maybe 4 to 4-1/2 inches from PAP and just above fingers it would go a little longer, and smoother. But maybe ask your pro to see what he thinks.  I am thinking about getting an Absolute Inferno drilled like that.

I bowled tonight at a synthetic house with a very tough shot. I couldn't even start out with my Columbia Action, it was more of a medium shot.  I bowled 204,192 and 158 with Ambush (stayed with it 1 game too long).  I don't have a medium ball right now so I used it extra game, then switched to Columbia Flipside Panic for a 196, 182, then used a 14 lb Brunswick Punisher for a 182.  There is a hole in my arsenal between Ambush and Flipside Panic, if that gives you an idea about the ball.  Even though it is pearl, it is still a lightly loaded particle which makes it a little aggressive.  It only has a little pearl mixed in to give it a smooth transition between oil and dry and to smooth out reaction on carrydown.  If you look at Brunswicks hook charts you will see it is similar in length and hook to some of the medium infernos.
I have a lot of ball speed and I can't use this ball for dry lanes.  Look at Bowlingball.com website to see drilling patterns for Brunswick.  They also give you a sheet with each ball.  

Brunswick recommends this ball for medium dry to medium oily lanes.  Even with my speed it plays for me on medium oil to medium-heavy.  A 5-1/2 inch drilling like you mention (with  a pin out from cg 3-1/2 to 5 inches) with pin over fingers would give you length, minimum hook according to Brunswick chart.

ps I really like this ball, it doesn't jump when it hits dry, just hooks too much as the lanes dry out.  If you can play inside lane, you could probably stay with ball longer than I can.

You're welcome.  I really like this ball.  For me it wouldn't be bad to have a second one drilled weaker like you are talking about. It is a really smooth rolling ball, doesn't over react.

Thanks.  I know that it can vary, but i was just trying to get a ball park idea.

Chris a 2.5" layout is good on a Ambush the only thing you can get up some hit and once you get some carry down you will diffently give up some hit. I have put this layout in some balls and added a nice size X-hole 3" deep 1" pass the axis to give it some pop.
