I still have an Incubator but only use it for my bridge hammocks anymore because - like all underquilts with corner suspension - it doesn't fit the shape of a GE hammock very well. A quilt that hangs from the corners will take on the shape of a curved half pipe, while a GE hammock is shaped like a hammock. The result is that you won't be able to eliminate all gaps. Underquilts like either the Warbonnet Wooki or the Simply Light Designs Trailwinder are a much better fit. There will be little to no gaps and there won't be any pressure on the head and the feet caused by the quilt suspension. If money is an issue, but weight is not, I would get a Trailwinder.
