Exactly VS gut 16g. has a limit of 32kg. which is just over 70lbs. I have yet to see a cheap gut able to take high tensions as such, as a quality gut being strung at high tensions allows for increased control and plays very well at high tensions. This is why a gut is not a gut, as there are differences. I have strung VS and Wilson nat gut at mid to high 60 lb ranges many times over not only for me but many clients as well, with no issues.You basically get what you pay for with Nat. Gut.
