Congrats on the New NX250!!
I love my Clark Camo NX250 and it was a good decision when I purchased it. ( I started with the Std. Clark Jungle Hammock).
I just received the Z-liner foot end only and I really like it. It isn't actually that bad to pack. I just throw it in the stuff sack with my Arrowhead camo Lost river 2/3 under quilt and I am ready to go for winter hanging.
I really haven't had a need for the Z-liner pocket insulators, but the foot end liner is great for winter.
I'll just leave the foot end at home in the other 3 seasons.
you can't go wrong with a clark.
