Yes it sounds redundant at first, but given how great 'Stim is this actually feels like a half-step up from Crack Shot and Lightning Reflexes. Consider the following:
With the advent of the Twin Laser Turret, and the use of Swarms to counter them, one ship has to defend against multiple attacks pretty frequently. Upgrades like Autothrusters and Lone Wolf that react to each attack independently are very useful in mitigating the wave of low-power attacks, but the Black Sun Ace can't take one and probably won't take the other. Glitterstim is the go-to here, but it's single-use only. And it leaves you stressed.
And that's where Wired kicks on. The turn you pop your 'Stim, the BSA isn't going to bother with any Wired rerolls since all those eyeballs just flip. But the following turn, you aren't committed to a green manoevre. Heck, you can get away with anything except a K-Turn. The Kihraxz has a solid dial, especially that 1-Turn, and being able to get some Attack and Defense rerolls for free is nothing to sneeze at, especially if you're worried about your PS5 pilot getting blocked. And of course, before and after your use of Glitterstim, it helps your K-Turns and punishes stressful upgrades lile Tactician and Rebel Captive.
This seems like a decent (and cheap!) combo right? It isn't self-stress the same way the A-Wing pilots can use the PtL/Wired combo but I've been looking for ways to use the new Elite upgrade.
