Everyone should know how to select and tie a number of useful knots. However, sometimes the right hardware can provide a little more speed and convenience than a knot. LoopAliens are like that. These handy little widgets make tasks like tensioning a rope for a tarp tent ridge line much faster to set up and take down. I like the rounded edges on LoopAliens and the fact that they can be purchased in kits, pre-packaged with Dyneema cordage.
