Well I throw the ball a tad faster then you do, I'm at around 17-18mph ball speed.
I usually play the Viper up 5 board with a touch slower then normal ball speed with my 2nd to weakest ball, BVP Rampage 1:30 drilling. As the pattern break's down I usually start moving left by the end of the 1st game. By the 3rd game it's not unusual to see guy's playing 20-8 but this depend's on how fast the oil goes away. I will sometime's pull out my weakest ball and maybe move back right some, this adjustment varies a lot because of the other bowler's on your pair. If you have experienced bowler's then the shot will open up and actually become a lot easier to play.
Shark pattern I play on a deep line. I usually start out with a Dull Solid coverstock ball, at that time it was my Storm Attitude Shift. I would start out the night playing 30 at the line, between 3rd-4th arrow, break point at around 13 board. Get the ball to the 10th board, say bye bye ball and get ready for your spare shot. The normal adjustment for me was to most left following the line. By the 3rd game I usually change ball's to a mild pearl, of course this will require some line adjustment to get back to the pocket.
As for the 3rd pattern you talked about, I still need to figure out that one myself. I don't do well on the Chameleon or Cheetah either.
