If you are refering to a winter cover...

I am going to get a net to go over the winter cover, this way after the trees do their thing in the fall, I can remove the net and leaves and stuff and reinstall the net only to do it again in spring and hopefully save days of work cleaning the decomposing, smelly leaves off the winter cover before I attempt to remove it.

If you are refering to a solar cover...

I dont have the patience...on..off..on...off
