Yes, in addition to bowling an adult junior league on Mondays with my daughter, one of my Monday night teammates and his son, I'll be bowling in my first sport league on Thursday nights in another house in Merrimack, NH. It's a trios league, and last summer they put out 6 different patterns for the summer, I think keeping each one in rotation every 2 weeks. The patterns last year were the following lengths: 15 feet, 20 feet, 30 feet, 40 feet, 45 feet and 50 feet. I'm guess with the two shorter patterns you can forget about using anything above light oil equipment and plastic (depending on the volume of oil...) and that with the 45 and 50 foot patterns, my heavy oilers will get a workout...but you never know.
I look forward to this experience, I know that my average will probably be closer to what I average on Tuesday nights then my Monday night THS, but I think I will learn a lot about my game and I'm a patient person, so I think I will improve as the summer goes on.
