I usually bowl in the Dutchman every year. Each year seems to be just a little bit different. In previous years the shot was usually a dry shot, with a medium-dry shot for teams in the Mt. Joy House.
This year it was more of a flat light oil shot in Palmyra that everyone I know just lit UP!! (If you are a decent bowler you should average about 240) Whereas the team shot was a medium shot that initially played like a heavy oil shot. Most of the bowlers I saw were using big pieces and getting over/under like crazy!! I was NOT one of them thank goodness!
My lowest score on the fresh shot, first game was a 201, which went steadily up from there, as we broke down the pattern. It's a pretty playable shot in both houses to me, and your scores should be high.
