Have never researched polyester line as its not available locally nor had I encountered it in my previous technical sports.
For those looking at using perimeter line for rescue and z-drag setups you will definitely want to research breaking strengths. The polyester mentioned above for a chicken line would be a poor performer for technical rope rescue on the river. It breaks at a measly 2800 lbs....no way I would put that on a z-drag for a raft stuck in a current. Nylon is often twice as strong but has all the flaws previously mentioned.
Will look into the tubular polyester for my next chicken line though....seems like a great material for purpose and environment.
