help with hammock selection
New to the hammock world... My bad back is pushing me to the trees. Anyway, I'm 6'0", 185#, backpack in the Southern Appalachians. Like to sleep on my back or side. I sometimes like to bend the hips/knees (not totally fetal position, but about a 90 degree bend a the hip). Trying to sort out if I'd be more comfortable in the RR or the WBBB. I've napped in an ENO double nest, and it seemed that the sides wanted to close in around me (understanding that this was an extra wide hammock). It was a hot, humid summer day, and seemed even hotter when nested in the hammock.
Looking for stability- don't want a tipsy feel.
Don't want to be "closed in" by the side walls.
I understand the concerns about staying warm at night, but we have some hot summer nights in the southeast. Is one of these more open and better ventilated?
Want to be able to lie on back or on either side with hips/knees bent.
Thanks in advance for any input. I recognize that some of these issues have been addressed before, but wanted to get any other insight before making the final decision.
