The skins help a little to keep from tangling, that's all.
+ 1 on small skins to cover the end cords. Tangles are your worst enemy. I've made them from silnylon, noseeum mesh, and cuben fiber.
I use 150 lb. test Spectra kite lines and 150 lb. Dacron kite lines for individual adjustable end lines (lots of tiny whoopie slings), but recently got an Exped Scout Hammock with end lines made with a continuous cord on each end. They run through a short ( < 6" ) sleeve which passes through the ring on the main suspension line. It's a tight enough fit that you can adjust the lines individually and friction holds them in place (so far). It's worth trying, because it saves a lot of construction time spent splicing.
The 150 lb lines I use are very light, but I think Zing-it or Lash-it will be safer. Go for it. If you try the single long line method you may need to experiment with constricting sleeves to hold the adjustments, once made. These lines are made to be slippery, after all. You can make a sleeve that's a bit large to protect from abrasion, then wrap it with bungee cord to provide the squeeze. Good luck, and continue to share the results of your experiments!
1st side is nearly complete, lashit installed, nest of strings removed, now to install anti-tangle loops.
A big "plus one" to what Diva B. said! NOICE!
Installed 2nd side lashit, one side of anti-tangle weave (which I now believe is unnecessary) and continuous loops larks headed to lashit locked brummels. Working with the 1.75 lashit was more difficult than I thought, I broke 20 gauge stainless safety wire, 24 gauge, floral wire each multiple times, and a knitters needle. That stuff is tough!
And it slept great last night! The body of the MH is 84" the lashit loops are 26.5" making the effective hammock length 137".
Fanfreakintastic! Looks awesome!
