Comments: I have used these strings in a hybrid with RPM Blast. Black Zone as the main and it felt fantastic -- great
spin, great power and a consistent string bed. I hybrid it with RPM simply cause I had a half set left over and I am sure glad I did.
Comments: If you are a fan of strings such as Savage black or Black Magic, then this string will be right up your alley.
It has a similar soft feel like the strings listed above when strung as a full bed. In terms of power, I would rank Black Magic > Black
Zone > Savage Black. Spin potential is about the same in all three strings. After about 6 hours of play, the strings show little
movement and tension loss.
