Maybe the answer to simulating gut (or find something better) isn't to use more fibres/filaments, but to use none at all. Has an air-filled string ever been created?
Think about it, you could take a stiff poly, thicken out the gauge a little, and have 20% of the middle filled with air. I think this would drastically lower the stiffness, not to mention it would impart a great pocketing feel. You would also get more power as the string not only rebounds from its position on the racquet but the air filling the space from the depression of the ball.
Polyester itself is stiff enough that the air tunnel throughout the string wouldn't collapse either, even when you cut one end.
I probably sound like a nut.
