I'm doing a project and I'm adding the most popular tennis strings in the string category. For example, The most popular natural gut string I would say is Babolat VS Natural Team Gut. For poly it might be RPM Blast? I know many think, like, ALU Power is better, but I'm talking the most POPULAR. That means Mantis, Topspin, etc. are MOSTLY out. Here's my list so far, feel free to add new ideas. Nat. Gut- Babolat VS Natural Team Gut Syn. Gut- Prince Synthetic Gut Duraflex Multi- Wilson NXT Poly- Luxilon Alu Power Kelvar- Ashaway Crossfire Any help is appreciated!
