That fist worth of slack is what's recommended for the Euro-style chains (like the Ofa EKO chains). For Ladder-style chains, tensioners are recommended. If I recall correctly, tensioners are recommended for DuoGrip style chains as well.
I've ran 2-link ladder style chains thousands of miles at 15mpj without tensioners with no problems. I see no way an elastic tensioner is of any value unless it's strong enough to require some form of mechanical installation tool to stretch it.
