My favorite way is pretty simple. For a 4' or 5" swim bait I put the swim bait on the main hook head as normal. Push the main hook all the way thru the bait until it is laying along the back of the swim bait. Take a treble hook (#4 works well) and put a trailer hook shrink tube over the eye of the treble hook. Then push the shrink tube onto the point of the main hook with the treble single hook facing down toward the bait. Hook this single hook into the back of the swim bait with the opposing double hook facing up. This set up will definitely improve your hook ups and will be most effective in open water or kept up over the grass. But using the treble hook it will definitely hang up more often.
For the larger swimbaits instead of a shrink tube over the eye I will tie a loop of braid thru the treble hook eye and then attach it to the swim bait main hook by making a loop knot over the main hook. The braid allows the tail of the hook to swim and roll like normai
