@bydand when looking at a Sloane list with only 4 total ships (Sloane + 3), I'm not sure if having 2 efficient fillers (30-36 pt range) is the right way to go, especially in that setup. If only 4 total ships and Sloane is on Lt Sai, then all 3 ships need to be pocket ace type (ex. named Strikers, Saber Interceptors, etc.). If Sloane is on Whisper, then 2 of the other ships should be pocket aces and 1 efficient filler. In your build, if I go all in on Whisper, I don't see the Alphas being that much of a punishment if I take out your most expensive and damage dealing ship.
In the Sloane Carrier + 4, you have enough ships to act as a screen and force the opponent to go through them to get to Sloane. In the Sloane + 3, I'm not convinced 3 ships is enough to have an effective screen while maximizing the 0-3 Sloane bubble, so then more of the ships in the + 3 should provide a higher threat to the opponent to make either going directly after Sloane or the clear end game / damage dealing / generally most expensive ship less desirable or a more difficult decision.
