MIDDY M-Tech Carp Commercial Line 0.18 – 5.2lb (300M) (with Hard-Shell technology) M-Tech is a unique co-polymer line, specially developed for both Method and up-in-the-water fishing on carp commercials. It sinks faster than mono once it is pulled under the lake water surface tension, with its 1:1.19 quick sink ratio (standard mono is only 1:1.07). M-Tech is extruded through a highly-polished die to create an exclusive Hard-Shell outer. It is this Hard-Shell technology that creates water-walker properties for float fishing, while also allowing the line to sink perfectly for Method work once it is pulled below the water surface tension. The Hard-Shell outer also assists casting, improves knot strength, creates anti-abrasion properties for extra durability and reduces refraction so light does not go off at an angle. M-Tech is also of a Method brown colour, to match the bottom of commercial lake beds. Supplied on mega 300m spools, with up to three reels capacity, M-Tech is the best carp commercial line to have ever been developed.
