I cut back to 1 league a week this year as well, with some occasional subbing on Wed. nights. It def. makes a difference. I used to be in a bowling alley at least 4 nights a week. Now with 4 y.o. and 9 m.o. kids, priorities have shifted a bit.
Yeah, I have had numerous 278s, 280s, 290s, 298s, and 299s. I have had 2 300s.
