[X] 0: Six Saucer Type-1 Phasers (Standard) [Avg Damage: 5]
[X] 1: Two Forward Photon Launchers (Infra++) [Avg Damage: 1.5] [Alpha Strike: 36]
[X] 2: No Aft Torpedoes
[X] 3: Two Engineering Section Type-1 Phasers (Infra+) [Avg Damage: 2]
Throwing in some votes for the less expensive options in the hopes that at least one or two of them will make it in. (other than skimping out on prototypes! Always prototypes!)
I'd like to point out: We don't need both forward torpedoes AND ten saucer phasers. One of the biggest uses for ten saucer phasers is boosting damage to the forward arc, which torps cover much more effectively. We do need to prototype photons, the sooner the better, so fore photons are the better choice.
The two engineering phasers offer better (ventral) coverage gains than ten saucer phasers, at half the cost, so I like those too.
