I bought just one of these to try. Love the core tech in these breakaway ropes. Allows me to enjoy a thinner, faster rope without losing weight. Which is very hardto find! I put it to the test and have been using a 9.5 to practice on roping calves about 2x a week. I enjoy how it stays in the heat and humidity but would be curious how it maintains flexibility in the cold. (I live in MN) My one small complaint would be its longevity. After using it for a month it still feels good to swing and lays nice on a calf but it's very frayed and worn.
