WHO IS THE TANNER PRACTICE SOFTBALL FOR? Facilities who teach hitting lessons every day will benefit from the Tanner SB1. The flat seams stay intact when used in pitching machines, and they will maintain their round shape (no eggs in your buckets!). WHAT IS THE COR VALUE AND COMPRESSION RATING FOR A SOFTBALL? As you progress in the game, you will find there are different types of baseballs and softballs. COR is the 'Coefficient of Restitution.' That's just a fancy term that describes how lively a softball will be off the bat. Softballs with a higher COR result in farther distances and higher exit velocity. The compression rating is nothing more the hardness of the softball is measured by the force it takes to compress the ball. IS THE TANNER SB1 THE BEST SOFTBALL FOR ME? The Tanner SB1 has a COR of .47 and a compression of 375 pounds. Ideal for amateur softball girls, home hitters, high schoolers and of course facilities where hitters are taking swings every day all day.
