I've had pretty bad luck with the "standard" nets from the local box & pool supply stores:
The plastic ones crack:
I'd replace the nets when they tear, if I could:
But, even the aluminum ones with replaceable nets fail due to the plastic edges falling apart:
So, my question:
Q: Where can I find better quality nets?
or, better still:
Q: How can I build my own nets out of stronger material (does anyone do that)?
