The houses I bowl at go with 41 and 43ft patterns that have heavy volume. The first 1 to 1-1/2 games, strong equipment is a must. Once the patterns start to break down, it opens up some, but not by much. Most people in those 2 houses all use stronger equipment such as the Nano, 916AT, Critical Theory, Invasion, Black Widow, etc.
The place that I am bowling at in a summer league is nice for a change because that house went with a 39ft pattern and all I ever need to use there is my Vital Energy, 505T, and the Brick. I'm enjoying that because that pattern allows me to open up the lane much more so than I would during the regular fall season.
