Redden Marine offers a small discount for internet orders at their website here
. Use the coupon/discount code "hammockforum". They are generally pretty speedy about order fulfillment so get your order in. The other alternative to Zing-it is "Lash-it". Both are great for tarp ridgeline and/or tarp tie-outs.
If you are using 7/64" or 1/8" Amsteel, you probably won't need to use any paracord sheathing. Both are sufficiently large that they won't cut your hammock fabric.
