Sorry, late to the party here, but here are my thoughts:
12X - so the lanes were dry, you have to learn to adjust. If you want to be a competitive bowler, you need equipment for all conditions. For almost a whole season, in my scratch league in Texas, I threw a Urethane Sumo because the lanes were drier. Did my average suffer, yes. But I thought I threw the ball better that year than the year before when I averaged quite a bit higher. The Urethane made me become more accurate to try and carry better. You could have done the same or even go to polyester if needed. You can give your opinions/complaints to the center, as long as it was done in a courteous manner, but take the opportunity while it is there to become a better bowler.
For those that have full PBAX leagues, who do you do it? We have a Sports/PBAX league here and we struggle to find bowlers. I haven't bowled a Winter league on anything but a Sports shot since I have had the chance to bowl in this league. I have seen my average go up from 197 two years ago, to 203 last year. I am hoping for another increase this year as well. I love the challenge and know I am becoming a better bowler, but we can't seem to get that across to others. They want their higher scores from THS (even though the THS in this house isn't super easy). Any ideas would be greatly appreciated.
