i like to use bungees which are thin and around the 3ft long mark, mostly carry around 5 or 6 of them. In the video i use ones which are around 18 inches long... Cheap and chearful, have 5 of those for me....
I prefer them as they keep the tension and are quick n easy to throw up a tarp... as i say, i carry paracord too so if i loose any bungees i can substitute them....
