You should be able to use the Wooki with any GE hammock you like. Just don't expect it to fit without modifications since 11' hammocks from different manufacturers can have different lengths. In this case it's actually good that the finished length of 11' Warbonnet hammocks is shorter than 11': it is much easier to lengthen the suspension than to shorten the Wooki.

The way I extend the Wooki suspension is with two thin daisy chain cords on the head and foot end. I clip the Wooki (including rubber band to have a predeterminde breaking point!) in so that it hangs loose under the hammock and work my way up until position and tension are perfect. This way I avoid accidentally over-tensioning and possibly damaging the Wooki.
