I removed the guideline between the two struts and lengthened the distance between them, and....
The BIAS fits fine!
The other benefit was that I was able to pitch my tarp on the struts too -- no additional supports (e.g., trekking poles) needed.
Distance between struts:
TOP: 136 in (345 cm)
BOTTOM: 92 in (234 cm)
I purchased a pair of steel O-rings and attached them to the guy lines and added an amsteel loop and a carabiner. This mod made it very easy to attach the different hammocks.
This is the BIAS Micro Weenie, 11 ft hammock. The under quilt is from Arrowhead Equipment.
