I always use a grigri2 instead of a backup knot when jugging. Once you get more than a few feet off of the belay it feeds itself and does not need managing. I am not the worlds most experienced aid climber but to me it seems more multifaceted (lowerouts, pendulums, etc) and is easier to deal with than tying backup knots. It is also a nice mental confidence booster.
Here you can see my setup...
