I do not have a superfly. In fact I have not camped in my new hammock yet but I've use my Noah's Tarp a bunch of times while tent camping and I've found that running a CRL works really nicely with the caternary cut ridgeline if you just don't tension the heck out of the ridgeline. I bring the tarp up to tension more by using the guylines on the corners going to the stakes. Is that crazy talk?
