I am bad about hanging the foot end too low as well. I have seriously considered hanging my line level on my ridgeline. I think it couldn't hurt, especially since as others have posted it can be especially difficult to eyeball on uneven terrain. I remember my first overnight in a hammock. I used tubular nylon webbing that stretched overnight on a relatively short hammock. I used my ridgeline to pull myself back up towards the head end every little bit during the night. Not the best sleep I've ever had. Hang and learn. I just finished sewing my latest DIY double layer yesterday and still have to set up my ridgeline. I'll likely have my line level hanging from it until I get more practice too.
