Cakes, I should have pointed out that the WM Ponderosa is being used with a Crazy Creek Hammock--very very similar to a Speer 8.5. This genre of hammocks was/is not known for asym lays like we modern hammock hangers know them. Yet I've slept many nights in the Speer 8.5 or the Crazy Creek and Ed Speer did two AT thru-hikes in one so they are not so bad. These are more 'trough' style hammocks. The advantage they have for deep winter camping is that they are less volume side to side-therefore less volume to heat....but they are as said 'trough' hammocks and as peapod users know who use the peapod on trough hammocks you still (most of the time) need a top quilt to fill in the gap between body and hammock edges because that space needs to be filled as well.
For your body size you can actually get asym just not as much as in a Traveler type hammock. Even my size can get asym but it really is minimal for me....all that said, I can get a flat lay in one and even get fetal.
Something else, this genre often had webbing through a sewn channel and this same webbing goes to the trees-so a dedicated tree hugger was often not needed and setup time is fairly quick, buckles made quick adjustment but is obviously heavier...............robust hammocks though.
