Instead of line-locs, I tie a bowline on one end of my guyline or ridgeline and loop that through the tarp tie out. I then use a six inch section of the same line material to make a Prusik knot that goes on the guyline. I leave the guylines on the tarp in a storm pitch configuration (just in case) but it is easy to move the lines just by pulling them through the bowline loop. When stored, the Prusik knots get pushed up against the bowline so they don't inadvertantly come off.
The Prusik knots begin with a loop formed with a double sheet bend so they never come untied. It is a simple matter then to sink a stake, slip the Prusik over the stake and pull the line taut. Easy and light.
