STROFT LS got developed on the basis of a new polyamide- alloy. The tuning focus rested on the goal to achieve a fishing line with a low stretch factor while ensuring the highest breaking strain possible. That is what the abbreviation LS (low stretch) stands for. The tensile strength values are the highest for any monofilament yet achieved (on average for all diameters between 0,10mm and 0,60mm). That applies to both - tensile strength with and without knots. In the low diameter range the values are quite similar to STROFT GTM. They continue to rise continually for higher diameters. STROFT LS 0,60mm for example has an astonishing breaking strain of 33,0kg ! Therefore, if you require a low stretch and maximum breaking strain fishing line and can accept marginally more stiffness of the line, then STROFT LS is your first choice. The increased stiffness causes higher memory which might be disadvantageous for some knot types. When one of these knots has not been tied correctly the line closest to the knot might go curly. The same effect might occur through line being pulled over a sharp edge. Having said this provided the effect is not too pronounced it can easily be rectified with a line straightener.
