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 vipers 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 core-tech can give, you wont break this rope. And like a viper, its the same every time Deadly accurate!
