Definitely not the most detailed or exhaustive resource, but it's still fun to see mentions of some of the older balls. I am in my my 30's, so I grew up during the urethane heyday of Nitros, Hammers, Cobras, and then I saw things transition with the X-Caliber, Turbo X, etc. Still, I think the ball I look back on most fondly from that list is the Gold Pearl Quake. I made a ton of money with that ball as a teen bowling adult leagues. It probably wouldn't do much of anything on today's conditions, but it would be fun to throw one just for old time's sake!
