I don't use any baffles in the second version and it doesn't cause me any problems. I just squish some down up around my shoulders when I get in and I'm usually good. If I move around a lot and it's cold, I sometimes need to do it again in the middle of the night, but at Trail Days the low was 34 and I didn't wake up at all.
But my insulation pocket also stops at my knees...if it goes all the way to your feet, you'll probably at least need one up near the end. Suggestions:
- Don't sew the baffles to the hammock body. Sew them as a pocket on the shell.
- If you always lay on the same side, you don't need the baffle to go all the way across or down the hammock. For example, my feet almost always go to the right side of the hammock, so I don't need any insulation on the left side of the foot end. That'll save a bit of weight, and cost of down.
Even if you sleep cold, you don't need the insulated pocket to go to your feet...just carry a sit pad or torso pad. Condensation isn't much of an issue down there b/c you don't have a lot of body contact on the pad (for me, at least). And I like the idea of having a sit pad anyway. Plus, a small pad is lighter than the equivalent area of insulation+shell you'll need for the lower half of the hammock. But that's just the way I do it...doesn't mean it'll fit your needs.
USE ZIGZAG STITCHES to allow the body to stretch w/o causing a hole in the fabric...since the shell and straight stitches won't stretch with the body.
Minimize backstitching. Try to sew the shell to the body in one long stitch, putting the backstitch at a place that doesn't get much stretch. Mine is at the head end on the side I don't lay on. Just inspect the perimeter often to make sure the threads aren't getting loose.
My homemade uninsulated Speer-type plus JRB and suspension system is about 34 oz. My down hammock is 19 oz. Add a ~6 oz torso pad and I'm good to the same temps...maybe lower, plus I have a torso pad that I use more often than I expected to just sitting around.
So the weight will be similar, probably slightly in favor of the down hammock if you insulate it full length. Pro is you have a sit pad and no installation or fit issues, con is you need to spend another 15 minutes sewing an uninsulated hammock for summer. Also, most Speer-types can be folded in half to use as a chair, just like the HH. Putting the insulation pocket on there makes this uncomfortable...so you'll have to sit inside the hammock instead of in lounger mode.
I used 1.9 oz untreated ripstop for the hammock body, and 1.1 oz DWR ripstop for the bottom shell. I think I've had 1-2 quills come through the untreated ripstop after...I dunno, 20 nights (?) in this one. Less leakage than I've had with my down bags and quilts.
