Before I place an order for my first Hammock (hyperlite), I'm trying to decide what size snakeskinz to get (among other things). I believe the #4 will fit both the hammock and tarp inside going from email correspondence, but I'm not sure if it is best to store them both together. With no hammocking experience, its tough to know how I will prefer to set it up. I'm sure its infinitely easier to just have them both together, but perhaps it's best to have them stored seperately so that you can have more space between the top of the hammock and tarp to avoid claustrophobia and other issues that I can't imagine now. If it's best to only keep the hammock in the snakeskin, then I'd probably need a smaller size snakeskin then?
