## Questions & Answers

**Q: What is the difference between black knight and firewire**
A: Good question! We usually recommend these 2 strings based on playing level. We believe Firewire fits best for players with a NTRP between 3.0-5.0 (intermediate -  advanced level) where Black Knight fits better for players with a NTRP from 5.0 and up (advanced - high performance level). 

Main product differences:
- Firewire: Highest possible spin potential, more powerful.
- Black Knight: For players with high racket speeds, offers great directional and depth control, high durability.

Both strings offer great tension stability and are not overly stiff for a polyester string.

Hope that helps!
