My favorite string used to be 4G for main / NXT or NRG for cross. I used this hybrid for Prestige MP, Pro, AeroPro Drive, Wilson Blade 98.... But recently after getting Wilson Prostaff 97 RF strung with 4G/NXT, I found this hybrid is so awkward for me: muted without feel. I don't know why its feel is so different. By the way, I am searching different feel hybrid strings. I think I need more crisp feel string. Let me ask you a question. What kind of string(hybrid) do you recommend?
