Ive had a few tarps, some with line locs/guy runners I leave on, to use with trekking poles, and others without. Actually on the attachment points of the tarp, I have small 2mm dyneema loops, in a simple overhand knot, so I can take extra line with me, and just do a simple loop to loop connection. Normally with 4m guys. I use a selection of hitches, I prefer a simple truckers hitch, for a ridgeline, [10m] where you can double or triple the mechanical advantage, with some smaller diametre dyneema, attached permanatly via prussiks. Again use a slippery hitch, or a tautline hitch to attach to the pegs/trees. Hank the line in a figure 8 round thumb and little finger when packed away.
I also carry a selection of different cords and line in a stuff sack. So i have cheaper 'throwaway' stuff with me, for tieing logs together, for instance, using a simple butchers knot or arbor knot.
