So in an odd stroke of luck, I was donated a Hot Rod. The manager of the center I bowl league at was cleaning out the old lockers of people who haven't shown up in 6 months or more. One locker was behind my pair, and he was chucking everything out and I was like, "Yo, Can I get the ball before you chuck that?" And he handed it to me, woo. It's a bit tracked up, but nothing a resurfacing couldn't fix. The only problem is that it's only 14lbs. Before I go and resurface this thing, would the difference in weight to my other gear be too much? I've seen some people switch between 14 and 15, and 15 and 16. But I throw 16, would a jump between 14 and 16 be too much?

And also, would drilling this ball RICO be fun?
