I have bowled on the pattern, but I don't recall the length.  However all of the challenge and sport patterns are most punitive to bowlers who like to exploit swing area.  Your style sounds like it will not be penalized as much as some providing you can repeat shots.  Biggest thing you might notice is that spares, especially left side ones get a lot more tricky than on house shots.  If you don't already use a spare ball, and plan on bowling more tournament patterns, I would suggest you incorporate one in your game, and use it for all of your non double wood spares, not just corner pins. 

it 43' and 3-1 ratio
the shape of the pattern and the length of oil would suggest that you play around 10 to 13 at the arrows and about 12 at the breakpoint (very generally speaking)
your 1st few practice shots would tell you what ball to use and where to play
