Hey LM,
As far as I'm concerned mooching and jigging require two different sticks altogether...
A jig rod is required to lift a jig with minimal effort and have the backbone to set the hooks hanging on the lead jig deeply into the grill of a salmon. Think 7'6' one-piece 15-50 lb rods.
A mooching rod on the other hand needs the length and forgiveness to allow a wary chinook to mouth the bait without feeling the rod flex. I like a 9'6" to 10'6" rod for mooching.
Perhaps our resident Mooch Master Robbo Endsley can weigh in on the subject
