Coolhorse was lucky enough to get in a limited supply of BadA$$ Polygrass calf ropes.  This sparked a discussion about measuring sizes on ropes.  Grass and Polygrass ropes are traditionally labeled by size according to the number of strings used to make them.  These particular ropes are 57's, meaning there are 57 strings, or three strands each composed of 19 strings, spun together to make the rope.  Poly calf ropes are traditionally measured by diameter in millimeters and team ropes in fractions of an inch. 

With all these different systems, how do you know what size a 57 Polygrass rope will feel like?  We asked local calf ropers and consensus is that this batch of BadAss 57 Polygrass ropes have a diameter similar to a 10.25 poly calf rope, but they are a little denser so the weight is closer than that of a 10.5.
