I used 0.8mm waxed twine after trying kite kelvar string which only lasted 6 months before starting to fray, it was 1mm tho so this could have caused it and it was from china so not sure of the quality, but now a year on and no sign of the 0.8 fraying ![Thumbs Up (y) (y)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
