@VoA damn you man! You’re concierge. We don’t melt or CCU, WE ADD!!! LOLOLOLOL. But if you’re taking opinions;
I’d say one of the VG. Since you have all 3, I’d recommend keeping the base for actual anti fighter anti med to large ships. Keep the Sentinel for its wild weasel role. Melt the Harbinger as the Inferno will punch more than the Harb, and you can keep the Eclipse for Alpha strike.
Or.... dump the Eclipse. It’s a stealth, strategic alpha strike platform. 3 size 9 torpedos and then go back to base to restock. With the Ion, you can stay at bay with unlimited ammo and you have a better chance to defend with the INCREDIBLE amount of missiles and shields to bug out. Or the Inferno, for amazing Dakkkkka and brrrrrrrrrtt, all the missiles CaptainNero, and get this.... same MED shields and components as a MIS.
KEEP THE MIS for its great value as it was sold pre-CIG bS mark up. $165/175 whenever you got it, gets you a great high value cargo transport gunship. Plus ...... “fire everything” CaptainNero missiles load out WITH dakka!!!
