when you can peel the layer back its good stuff.
not had a prob with any knots myself. always use knotless knot on stripped back part and figure of eight (steamed) on the other end. for ease of use i prefer stripteaze by ESP, although it isnt as rigid as the hybrid (or coated in flurocarbon), its still good
if anyone knows of a good way of stripping the stuff can they let me know!
