When I fish a dropper in the salt, I tie a surgeons loop in a tippet section about 1/3 of the way down and attach to the leader via loop2loop.
I cut the dropper section back to about 4" and fish two streamers, small on the dropper, large on the point.
For trout I like to have a streamer chasing a nymph. I don't know if the fish care, but it looks right to me
