I use a single #6 octopus hook. I tie 30lb braid to a #6 octopus hook, and then I use a large sewing needle to thread the braid from the tail to the main hook. I tie the braid to the base of the main hook and then soak it with super glue. I've had really good success doing this with Storm 360GT Searchbait Minnows in the 4.5-inch size. They're a bit more expensive than Big Hammers but they seem to hang up less on seaweed. I think it is the shape of the head.
For both fish, the trap hook was in the lip or jaw. See the closeup below.
For the retrieve, I typically do a slow retrieve making sure I feel the bottom, then a pause and then a twitch. The bites are usually in the pause or just after the twitch. The bites are just a tap. They are almost hard to tell apart from the lure just hitting a rock. But there is usually something different about the bite, it's just a bit sharper. It's hard to describe, but after making a thousand casts, you just know that it is different. I usually wait for a moment and then slowly load up the rod until I feel the weight of the fish.
