So I broke my bg -80 again and replaced it with the NBG 95 at 25 LBS of tension. I had previously tried these on a black knight pc-20 at 24 LBS but not muich feeling felt numb. But on my NS9900 at 25 pounds it's comibnes that crispy feeling of brand new bg-66 with the durability of the Bg 65. Love these . Whoever has trouble with broken strings over and over try these
