guys more experienced than me can chime in hopefully, but after busting off a real nice fish using #30 I now use #50 and see not enough of a difference to say #50 is too heavy hell i even got cut off in the reef with #50 the other day
(maybe certain days idk, so far so good though since mid way through last season)
I also use a baitcaster set up...i don't need the sensitivity from a spinning reel, i keep me finger tips on the line and i can feel everything and then have the power, that a small/medium spinning reel can't give you, to get that fish off the bottom.
I've never even looked back at a bait rig since i started using a jig. I can 'explore' the structure better without getting snagged as much and imo you have a better chance of hooking and landing the fish with a direct connection and no swinging sinker.
There are depths and current that would be tough to use the jig in, but it doesn't have to remain perfectly still from my experience. you just kind of let it slowly and controlled sit and roll down there slightly moving it to a different spot every now and then or maybe tapping it on the bottom a few times to kick up some crap.
