I'm sure anyone you ask would probably give you a different answer, but here's my thoughts on the subject.
Generally speaking, when retrieving, you want a steady retrieve, just fast enough for the plug to have the correct action. If you're using braid and have a relatively sensitive rod, you should be able to feel the action of the plug, otherwise watch the plug as it gets near shore in clear water and see how fast it needs to be retrieved to have the correct action.
Many times, though, a momentary pause in the retrieve will trigger a strike. Depending on the composition of the plug, when the retrieve is paused, it will either suspend, slowly float to the surface, or begin to sink. I've had the best luck with this type of plug if it is one which slowly sinks when the retrieve is stopped. Many times the hit will come as it drops.
Learn the area where you fish, learn what underwater structure is there. Go there at low tide, get a good chart, do some snorkeling, whatever you've got to do, but once you know what's there, you can use that knowledge to your advantage. One deadly tactic is to cast your plug past said structure, and retrieve toward it, once your plug gets in that 'zone' around the structure pause your retrieve and let it hang in that zone. Give it a few twitches, start/stop your retrieve, etc. Fish that are holding to that structure will many times find this presentation irresistible. Another tactic which you can use to your advantage with a plug like this that has floating characteristics, is to use the current to bring your plug into that zone. Cast up-current from the structure, letting the current sweep your plug into the zone, use a start/stop retrieve to trigger strikes. If you get a hit, but don't hook up, avoid the urge to reel in immediately. Stop your retrieve and let the plug hang there as though it is a bait fish that was injured or stunned by the strike.

That's my 2 pennies. Hope it helps!!
