Discraft has a specific line of plastic called FLX (Flex) that specializes in grip and absorbtion of tree and basket hits.
Ron,
I just got an FLX XL, and I can relate to what you are saying. Maybe just a little to flippy to be accurate. I want to try a regular esp/or zline instead. It does laugh at the sight of trees however. I have hit/knicked a bunch of trees with it and no sign of damage whatsoever.
