I do similar, but with a 3 hook rig in the river. Working with a "Rhys" something anchovy helmet, the bend of the second hook is about even or just past the tail of the bait and the bottom hook is doing it's best tiny dancer impression downstream of the bait by a couple/three inches. For two hook rigs in the ocean, the trailer is generally in the same spot, so just a lot more spacing between the two hooks. Had several fish this year where only the trailing hook was right at the tip of their nose.1.5-2 inches from the tip of the lure or bait tail to the hook eye has been working well for me.
Seems like most bites stick this way, getting them to the boat with barbless hooks is at the anglers discretion of course.
