I'm not sure I get it about polys. So it lets you hit really hard and get more spin without hitting the back fence or otherwise looking control, because it's not very resilient. But it goes dead quickly and loses tension? Isn't dead good in this instance, or do you want to be just mostly dead like Wesley in The Princess Bride? Isn't this performance like what you'd get from good old monofilament 15 nylon like they put in cheap pre-strung frames and everybody makes fun of? Is there a placebo effect thing going on with this? Or am I missing something?
