Odyssey Ai-ONE SQUARE 2 SQUARE Putter MAX STRIPE Custom 35.5 inches Mid-Length Grip: Mid-length, SuperStroke Zenergy XL Flatso 2.0 Plus, in good condition. This is a popular mid-length model of the much-talked-about zero-torque putter. Even I, who am not good at putting, didn't miss a single short putt, and it was stress-free! I used it for two rounds after purchasing it from Golf Partner. For those with yips. For those who are stressed about short putts in competitions. It's mid-length, so the counter-balance helps your hands move even when you're nervous! However, I couldn't fully utilize it (it's not much different from the AI Jailbird Mini), so I'm putting it up for sale while it's still in good condition.
