Cleveland products are always top notch.
The Gelback really dampens unwanted vibrations from mishits. Clean hits feel really good and crisp with enough feedback. The 'Zip' grooves are suppose to be 25% larger than the average wedge, milled to the maximum conforming dimensions. You really get a lot of spin on the greens with this wedge.
Due to the 'Zip' grooves, you may need to bring some extra balls if you tend to use this wedge a lot. Being new and learning how to chip, this wedge proved to be quite a challenge to use.
Yet another great product from Cleveland Golf. Great wedge if you know how to use it.
