I dont think it really matters how you rig them as long as they stay on the hook. And interms of one way being better than another or one bait being better, as long as they stay on the hook you are fine. I have caught steelhead on pink worms while fishers directly above and below me were fishing ghost shrimp...didn't help them on little bit! I think its more a matter of getting a decent presentation (worm, eggs, spin n glo, ghost ship, prawns, spinners, spoons, jigs....etc,etc,etc) into the strike zone.
BTW, I fish shrimp this weekend. I procured them red then stored them in a zip lock in the fridge with coarse pickling salt (maybe 2 table spoons). The procured colored them up nicely (after an overnight soak) and the salt toughened them up. They were just the shrimp ring type and I just hooked them thru the thick meaty part. They stayed on for a good long time.
