Putter Head Cover Needed or Not

I have one on my xg and it doesn't interfer with my game. I did also have one on all my clubs as I too hate the clatter of the clubs while walking along! These though got binned as it drove me mad taking them off and putting back after every shot! I put up with the clatter now, just driver, hybrid and putter have covers now! I also lost my sw cover during a round!
