but thats the whole point, you do not need to set the fighting drag as it should be set before your first cast then IF you need to alter it during a scrap then that is no different to the way you fish, also once you have set the rear clutch for the bait runner AFTER YOUR FIRST CAST, it also requires no further attention.
set your line to your desired tension( tight/semi/slack), rod in the pod, clip on your stows or whatever then one flick of the finger to set the runner and any more is just being a tart
