The only problem I have had this year with my CC net is the freezing rain. It froze the net to the ground and was almost impossible to get it freed. I bought the 1 1/4" smaller holed net and I am glad I did, my horses are hogs and I was thinking I could even go smaller. I use a metal ring feeder in addition to the net, I made the mistake of just using the net and when the bale collapsed they walked in into the mud, peed, and pooped all over it, basically ruining half a bale, and it was the biggest PITA to get the soiled hay out after that.
I definitely recommend using a metal ring feeder to get the most out of the net, and I also now put a pallet underneath the bale to keep it off the ground for the most part. I have NO waste whatsoever, and other than some minor issues with getting frozen to the ground, have had no problems with it, no holes, and I still love it.
