Any 45 foot pattern is going to really limit your swing area.  If you had a chance to watch the PBA guys on the 52 foot Badger pattern you have an idea of how to attack long patterns of 45 ft or longer.  The key is not to try to over power the oil and create hook where none is available.  Typically, end over end roll with low axis rotation coupled with the ability to square up and not head belly the ball at release  are keys.  Biggest mistake many people make is adding surface to try to create swing area.  All that often happens is that you create a small move in the heads without creating any swing.  I usually use a strong core, low rg shiny ball that will rev up and roll yet still give me some hold area.   

 A lot depends on the condition of your lane surface.  Older surfaces tend to be rougher between 10 and 15 board ( even if they don't look it ).  I have always had good luck starting very square up 10 board, and gradually making parallel moves toward 3rd arrow as the shot opens up.  If you have a bunch of heavy handed guys they may be able to blow a hole in the pattern, but it will take a game or so for the shot to open up very much.  In a short format like league, they will pay a price ( 2-8-10, washouts ) the first game that is too much to overcome even if they shoot a big last game.
