I use the cargo net type. The rope is nylon, which is capable of holding WAY more weight than a full 5-gal carboy. I used a couple of zip ties to connect the handles (see arrow) so it doesn't slip off the bottle when I set it down. I leave it on all the time, even when I wash the carboy. I liked it so much I bought another one. I'm 69 and have no problem carrying full carboys down into the basement with it. The handles pull up above the neck so you can hold it one-handed or two. (Note: the big open spaces you see on the left and right get pulled up above the neck when you lift the carboy; that brings up the netting part. ) The bottle is very secure, doesn't move around when you carry it. The carboy sits flat on the netting.
