Finskie, a guy you size could easily use the WBBB 1.1 single layer. With dyna glide whoopies Raul Perez has his down to 18.44oz. If used outside of bug season. Leave the tie outs at home for around another ounce savings.
I'm 185 and use a 1.1 single layer traveler and it certainly stretches, but not uncomfortably. I love it. Ill get a single 1.1 WBBB next spring probably.
I know nothing about Tree to tree's hammocks other than hearing on here that they're super comfy. I'd love to give one a try and its deffiently on the list.
