I do not remove the lines off my tarp. They stay on. I attach guylines to the tie outs at the ends of the ridgeline rather than hanging on a line extending the full length. I have a cat cut tarp which doesn’t have a big issue with a sagging ridgeline unless I setup the corners wrong. I don’t adjust the lengths of my lines when setting up my tarp as they are already set up for 3 lengths already and I found that always works. Basically there is full length, half length (where both ends go on the stake), and short length (18″). If the stake won’t go in, I pull the line tight and rotate it in an arc until I find a place they will go in.
That said, the lengths at the various tieouts are not all the same. Though I use a MLD Grace Solo Tarp, I don’t use MLD’s line recommendations on their website (though they aren’t bad, just a little shorter than I prefer). I prefer Gossamer Gears old recommendations for their Spinn Twin tarp from several years ago. They recommended: 7’ for the front peak pullout, 6’ for the rear peak pullout, a nd 6 – 2’ lengths for the wall corners (4) and the mid-wall pullout. I also add a 12-18″ shorter line to these lengths (for the corner and side guylines) that I use to get the short guy length. The ridgeline guylines don’t get the short length as it has no use there. What I mean will hopefully be shown in photos at the end of this post.
Gossamer Gear use to also have a pdf for knots. I tie a bowline knot on both ends of all my guylines which basically makes a small loop at the ends. This allows me to loop the line through one of the loops around the tarp’s tieouts and makes it easy to extend those guylines by adding another length to it in a similar manner by looping the next guyline around the loop at the end of the other one. So the corner and side guylines all have a short guy line attached to the tarp and I then add the normal length as an extension to those shorter lines. For a full length setup, I pull the line tight as far as it will go and put the non-tarp end loop over the stake. For my half length pitch, I pull both loops of the guyline out to the stake so the line is doubled up. For the short pitch, I use just the loop at the end of the short length guy line on the stake while the rest of the longer line just sits on the ground not doing anything.
I took some photos of my guylines to try to make it clearer what I’m talking about. I’m too lazy to resize the photos to fit in my post here as the site rejected them, so I uploaded them to my Tarp/Bivy Setup Photo Album. The guylines closeups are the last 6 photos in the album. If you look at the photos full size, there should be a tiny comment in text explaining what the photos are.
