What happens when five strands of low stretch poly fibers are woven around a solid braided core? You get a rope with speed and snap as quick as a viper's strike, but with more consistency and less stretch than any calf rope on the market today. With the feel of your favorite poly-grass and the strength and stability that only Coretech can give, you won't break this rope. And like a viper, it's the same every time: Deadly accurate.
