I have fished them quite a bit and found that most of the time I didn't need the trailer hook. I have been fishing the SK bleeding bait series that has the tip of the trailing blade about even with the back of the hook. I found my hook up ratio to be a tad better than with cranks. If I had a spinnerbait where the trailing blade extended a good bit past the hook, I would add a trailer hook
Two things I have found, on clear water blade color can be huge, I have not caught a fish with anything but silver/chrome blades, regardless of sunny or overcast. Another thing I found is adding a huge trailing blade can be dynamite during post frontal conditions.
Also with the braid go with a rod with a softer tip or loosen the drag a decent amount. With how hard they hit these, it is not uncommon for the bait to fall right out because they have a hole/tear where the hook penetrated. Steady pressure is a must. Also like cranks, bumping them off of cover can be a very effective trigger.
