I have found I like Profleece heavyweight green back the best. I don't find any of the ribbed backed non slip ones last as well and go very flat compared to a good thick woven back .
I am still using dark green pieces for my lot that are 15 years old, where the pawprint ribbed backed have given up the ghost.
I now buy the pretty non slip stuff only to give to new puppy owners in my puppy packs.
I have bought some more for when I want to replace the old somewhat chewed pieces, this time in burgundy LOL
