Now that i have my new ebonite Overtime. Now which is the best spare ball all around from ebonite or any of the manufacturers. My current "spare ball" is manhattan rubber, which can do most spares, and is my primary if the lane is not oily enuff for my overtime. Now i need a spare ball which is suited for wet/dry to light/medium/medium-heavy. And i understand that the spare balls arent that pricey, but which is worth my money. Thanks!
