I can say that I've bowled on lanes where we watched the laneman try to put oil down. Nothing ever came out! We found out during practice. Balls hooking BEFORE the arrows!! We were like whoa!! It was a painful night for sure. 170' and 180's were looked at like 260ish games! Later that week we found out the wicks in the old machine were clogged and had never been cleaned. Three weeks later we had a brand new machine....thank goodness.
In another league, a trios league, the lanes had heavy oil from 10 to the gutter. The rest of the lanes were dryish, too dry for a medium ball. I had just started using 10 as my preferred target area so this was disconcerting to me! Went into my bag and pulled out an old Brunswick Monster pearl ball. It was drilled pin down, almost in a rico position but not quite. I played straighter, revved the ball up and let it just spin off the end the pattern, going down 7. I got swisher strikes all night long and ended up shooting a 702 set! My teammates loved me because they struggled all night but we
swept the team bowling us! Never saw a look similar to that again!
