Which of these strings would be the best combination to the cab20 special? my current string is BG65ti at 20x18 pounds of tension. It provides a lot of power and a really loud hitting sound compared to the BG66 which I have on my other racquets but it has very poor control. Which of these strings would provide better control but still have a lot of power? BG65, BG66, BG70pro, or BG85?
