Sounds like you purchased our Poly E handle.
Our core mainline (Power Cord)has a higher tensile strength than the Accurate Jacket. The Accurate Jacket has a neoprene core, where our Power Cord has a solid spectra core. I've also been told that because of the Accurate Jacket not being a solid core, the rope does actually have some stretch to it.
If anyone has questions, feel free to email me.
