Most of my team felt the showcase lanes were a little slicker. I thought they were pretty close. It was odd that when my ball came back on the ball return at the showcase lanes, they were covered in oil. It wasn't as bad at the stadium. Some guys on my team even bought new towels because there was so much oil on their bowling balls. Makes me wonder if they use different oil upstars and downstairs, but that is probably a reach. If you are working with Matt, don't plan on much on lane practice. We had less than 15 minutes, and others I talked to said the same.
I didn't bowl the bowlers journal, so I have no input.
