Ridgeline - 15' ZingIt/LashIT with a Dutch Zingerz on 1 end, clipped to the tarp X2.
Tie-Outs - Small Loop of shock cord with a triangular line lock (from the HF store) threaded on it. This is larks headed onto the tieout ring (in case I want to change it out). Then I run a 4-10 ft length of Zing It thru the line lock with a fixed eye (for the stake) at one end, back splice at other end.
Simple, light, easy to modify or swap out. Have also used a prussick inplace of the linelocks if you are trying to minimize hardware.
