I still remember sitting in my buddy Chuck's Pro-Shop in Wisconsin with every manufacturer's ball catalog open in front of me, looking for a couple of balls with a different reaction for my bag
I had books all over the place, sheets falling out, and a pad of paper with cryptic notes and page numbers scribbled on it. I was thinking to myself, there MUST be a better way.
Being a programmer by profession, I went home and spent a week extracting all the ball information from the manufacturer websites, and put it in an excel spreadsheet, this way I could just sort them by RG and Differentials, and find what I was looking for quicker.
That little spreadsheet became quite a hit, friends at the pro-shop were soon looking at it to find equipment for themselves.
