So generally Stealth Device is best on ships that can effectively token stack multiple focuses and evades or arc dodge very well or both, which the Scyk isn't good at doing either of, although Attanni Mindlink will help you token stack more effectively. So generally Pulse Ray Shield is probably the better option.

The two exceptions I find is if you're running a small swarm with Serissu, Serissu will often be targeted first, and Pulsed Ray Shield only works if you survive the initial onslaught, so having the extra defense earlier on. The other exception as Wazat mentioned is Laetin A'Shera
