Has anyone seen duck decoys with a unique or different anchor system?

I currently use heavy mono with an attached weight and then wrap it up around the keel of each decoy. In between hunts I find that sometimes the mono comes loose in the decoy bag and I get several tangled up. This sucks to discover this at 5:30 am at the next hunt. When I try to prevent this by wrapping the mono real tight around the keel it's difficult to undo and cold fingers don't help!! I noticed the ACE anchors, but I was wondering what else is out there? When I go to the sporting goods store all I see is mainly generic CRAP (just like I've been using)!

Thanks!
