I used them all last year, as for the snow it piles up a little higher than without, but I like just uncliping the bungies and pull the covers off the end of the wing it make a nice neat pile of snow out of my way. A foot or more I knock it off with a broom and then slide the rest off the end. In late winter with the melting freezing cycles you will be thankfull that you have covers. Ice doesn't stick to them at all!! I remember flying one week when everyone around me was wating for there turn in the hanger to defrost. I like flying at sunrise today was 25deg and thick frost, I was wheels up at 6:30.
The only other thing about the covers they catch on where the flaps and alerons meet, I purchased two kids swim noodles $1.00 each. cut them down the middle and slide them over the trailing edge. then put the covers on over them.
