I actually bowled in college from 1995-1999 (Kansas), so I know exactly what you're talking about. Instead of people throwing a medium ball and gradually breaking down the lane condition, everyone starts with their newest, dullest finish ball and blows it up in 3-4 games.
Playing outside 5 is very difficult by the end of the day and would take someone of extreme talent. This usually is not your best option.
Playing inside 5th (and sometimes 6th) arrows is usually your only option. When I was in school, I used 5 1/2" to 6" pin distances in 90 and 105 degree layouts. The 135 degree will be pretty lazy downlane for the launch angles you're trying to create. Obviously you want to make sure your choosing balls with weaker and polished covers. From the Ebonite family, I'd suggest a Whirlwind, Big Time Pearl (slightly stronger side), or a Blue Ice (slightly weaker side).
Good luck in St. Louis! I always bowled terrible there when everyone else struck at will.
