I have a stash of Thirsties duo covers that I have used on my DD and am considering what to get fro the new baby. The velcro on the thirsties has gotten really fuzzy and has lost much of its grippiness. Any suggestions for a velcro cover that might not have this issue? I can't stand snaps, so that isn't an option. I am interested in the new Bummis SuperLite covers, but have read mixed reviews (I have a thread about them down the list from last week). Any others I haven't heard of?
