Over the last year, I have noticed a change here in my area (Southern California). I mostly bowl at AMF or Brunswick brand bowling centers, and it just seems there is so much more friction than in the past. I am not sure if this is intentional, or possibly lane surfaces wearing, and just not holding oil as well as in the past. Over the years in practice, if I got out a weak reactive or urethane a 200 would be a good score for me, now, 250's with my urethane Natural Pearl are not uncommon, and if I try to use medium strength equipment, I'm playing 4th arrow, and frustrated by the lack of hold in the pattern. I've asked the center managers, and they aren't aware of a policy from corporate. Haven't had the chance to speak with the lane men about it yet. Wondering if anyone else is dealing with this issue over various houses.
