I'm not on
@Anarchy99 level, but I've been in bowling leagues off and on for the last 20 years, have a couple of custom made bowling balls fit for me, my own shoes, etc. At my best my average was 225, and I would absolutely take $50/strike over a lump sum.
That's what used to get me when I was more active than now. Guys would show up to league night or tournaments with 8, 10, 12, 16 different bowling balls (and bowled like 5-6 nights a week). They had these giant wheeled cases that looked like they were moving a giant safe. I had my main ball and a plastic ball to shoot 10 pins (which I rarely used) and only bowled on league night. Once I had a family, I didn't even practice. Just those 3 games a week (plus an occasional tournament).
It didn't matter what the lane conditions were, which bowling alley I was at, what oil pattern they used, or how the lanes changed as the night progressed. I just made adjustments. I learned how to bowl on wood lanes, and every lane had different tendencies. Some nights, I had to start all the way on the left on the left lane with massive hook, and all the way to the right throwing a straight ball on the right lane. You had to learn to read the lanes and adjust accordingly.
Nowadays, most houses use synthetic lanes, and all the lanes usually will react pretty similar. I used to laugh at guys who went through 8 bowling balls trying to figure out the best one for that particular night. Sometimes, those guys would figure it out early and have three games of 250+. Other nights, they couldn't figure it out and had 3 games of under 150. I remember one guy went an entire night without a spare. It was strike or an open frame.
One of my favorite (READ AS: least favorite) memories was when I bowled in a regional PBA event. In terms of accuracy, I was ON that day. Every single shot I threw was flush in the pocket. Never went high, never went light. It was like I was throwing hand grenades right in the pocket. But I could not buy a strike. And I do mean I could not get a strike. At all. In 3 games. I mean that LITERALLY. I got a nine count on every single ball for 3 games. Take your pick, solid 7 pins, 8 pins, 9 pins, ringing 10 pins. I shot 190-190-190 on 30 straight single pin spares. No matter what I did to try to make tweaks or take a different line to the pocket, my ball ended up not carrying (with pins flying all over the place).
IIRC, there were 4 of us bowling at the same time. Each of the other guys had a 300. The worst part was those guys were wild as all get out. Brooklyn strikes, up the gut strikes where pins fell for no reason, missing the headpin and having a pin fly and knock pins forward, just a bunch of lucky breaks. They all thanked me profusely for taking one for the team and giving them good mojo. That was probably one of my top 3 most accurate series I ever bowled (yet I had for me one of my worst scoring totals). It happens.
