Don't know about serious but certainly at a competitive and collegiate level π
The reason I have so many clubs is due to be a tester, basically a guinea pig, for a few golf labs and custom build shops. I was one of 5 people who would test all the new equipment and tech that came out every year in the late 90s - early 00s. I was instructed to build clubs to custom specs with different shaft and club heads to test for feel, dispersion, distance, etc...
Since there were so many different manufacturers of club heads, shafts, etc...it made for many different variations.
Afterwards, I got to keep all the clubs which were built to my specs, hence why I have so many ππ
And yes, it will be a pleasure to play a few rounds together in the future πββοΈβ³
