I just got some for my lanyard recently, the selling point for my was the "enhanced grip", something I really like for my lanyard and I'm not disappointed, very nice in the hand new and I only expect it to get better.
20' lanyard so I don't have any opinion on stretch.
I like it with my runner in SRT, I bought a discounted rope do its a bit shorter. Definitely has a better grip for your hands than many other ropes. I prefer it over my blue moon so I use the blue moon as a retrieval leg on my canopy anchor
