That depends a lot on the conditions you are talking about

a 35' pattern would be 1 ball
a 45' pattern would be different
and a house shot could also be different

without knowing the above info, typically, symmetric earlier rolling pieces work best for me when i need to go up the boards

The ride is a beast when you can play up 5 with it. Got mine pin down and it hits like a tank.

Symmetric with a smooth arc motion is what I like best for this.  Plus, a dull solid cover that reads a little earlier helps blend out the pattern at the same time.

that's quite a bit older technology
and I would bet wouldn't do a whole lot on today's medium to heavier patterns OP is looking for
It was great on older wood lanes though

I recommend the X by 900 Global.  I threw it on Abbey Road at a demo day and even on a pattern like that the pin-down ball I was using had a hard time hitting flush in the pocket going straight up the 3 board.  It kept hitting light or hitting the 3-pin in the face.  To compare, my original Gamebreaker was able to hit the pocket flush or high flush from the same line.
Note: I am a little speed dominant (but plenty of revs).

low rg, low flare layouts, but you have to have a release that compliments what you are trying to do. You cant have 60 degrees of axis rotation and expect to go up the boards for very long as the heads break down, even on a house shot.

Properly used, I am betting it would still be able to get the job done.  No matter the oil, many patterns actually still allow for the accurate players to score from the weeds. 

I know the last time we had an office party, I made the mistake of NOT having it and wished I did when even a Sonic X was too strong.
