I leapt into the NX-250 for my first camping hammock too. My kids love it so much I had to buy a second one (just received it this week), Z-Liners and all. Tried to convince them to try a WBBB or something else but they insisted. Although I can only take one kid camping at a time until I buy more. I did try an ENO DN to see how I like hammocks first but couldn't go back to ground camping now. I leave the Z-Liner in all year, even in the tropics (slept 4 nights near Townsville, Northern Australia in December which is our summer) I didn't find it too warm, one night was a little warm but bearable and by morning I was very confirtable. Doesn't pack down as small as I'd like but isn't too bad. Although the stock suspension is actually pretty good I did swap to a DIY whoopie setup, I can adjust it just as well as the stock even if I have to double the whoopies over one or 2 times to get them short enough when the space is limited.
Enjoy your Clark although you'll always wonder what the others are like. I know I do and will probably give in to temptation one day and buy a couple of different types just to see what they're like. Although I have to wait for funds to accrue a little before I try too many, otherwise the wife may get a little cranky.
