The Stiff vs. Flex Handle baseball bat debate is the centerpiece of the dispute between baseball bat manufacturers and a leading cause of confusion among baseball bat consumers. I wish Mythbusters had included this in their baseball special.At least they taught us a corked bat actually reduces batted ball speed.

Here’s how to understand the rating for baseball bat handles. 100 is the stiffest handle rating and a handle with maximum flexibility will have a rating of 60. You’ll see ratings anywhere between these two extremes. Unfortunately, the majority of manufacturers do not provide the exact flex rating for their bats, just that they are stiff or flex handles.

Manufacturers like Easton and Demarini have pushed the benefits of the flex handle design for years, while others like Louisville and COMbat push the benefits of the stiff handle design. Two completely different designs stating they’re superior to the other. Will someone please hit me in the head with either a stiff of flex handle bat? Some manufacturers, like Easton, have recently begun to offer both flex and stiff handle versions of the same bat.

The flex handle philosophy says it’s better because “whip action” allows the bat to uncoil and release energy stored during the swing and increases the bat speed up to the moment of impact. Whip action is the bending of the bat when brought back and then swung forward before the point of contact. The top of the barrel is supposed to move behind the handle when it’s brought back and then move in front of the handle when it’s swung forward. Think of a diving board and a golf club as examples. See photo demonstrating the whip action of a golf club.

Stiff handle manufacturers say that stiff handles allow the trampoline effect in the barrel to be more effective thus improving batted-ball speed. The premise is all bats flex on contact (which is true) but the stiff handle makes that barrel flex more pronounced on contact and increases batted ball speed. Also, that rigid handles hit balls faster because a flexible handle messes up your swing, and if not timed exactly right, can actually reduce batted ball speed.
