Tourna Black Zone Is a low powered co-poly that offers remarkable precision on full swings. With its extra smooth and slippery surface, this one snaps back into place very effectively in order to impart more spin to the ball. Though it feels very crisp and quite firm, we found this one to have above average comfort for a poly-based string. Players looking for a low powered control string with exceptional spin potential should love this one.
