So, question.... I was on the Cactus Ropes website, looking at the different 3 and four strand ropes. Why are most of their head ropes 31 inches and the heel ropes an extra five inches? Why is there the difference in the two? I figured the head ropes would be longer because all the heeling I've seen has the heeler right up on the backside of the steer.... just don't understand the difference I guess. Also, why are the calf rope lengths even shorter still? They are all 28" from what I could tell.
