I'm a recent convert to the 0.68mm strings after feeling more control come off the BG80. I was tempted to give the NBG95 a try because of the color (Cosmic Gold!) and got it strung on my newly acquired Toalson Camblade Rev 2.
Right off the bat the string has a nice feel to it, something very similar to the sensation that I felt from the BG80. The clears were beautiful and the smashes came off the string bed after a period of holding. All that translated to a little more control than what I feel from the NBG98 which was strung on a racket I also brought to the court today.
Could this be a new discovery in my playing preference? Only time will tell as I spend more time with the Yonex NBG95 and BG80.
