Get a spool of the Russo brand line on e-bay, the smooth stuff. And get a small bucket to keep it in water with some bleach. All the square, triangle, and star lines I've ever run break too easily. And if you let your line get too dry it'll break a lot. I string trim a lot of gated pipe every summer to make irrigating easier. This is the only thing I've found yet that works.
From the quality and strength of the spool itself to the actual materials used to make line, this product is nothing but heavy duty! Why buy from EPR Distribution?. The best products, the best prices!Our team works hard to find you the best deals and provide you with a wide selection of products.
