Yep. 6x Crack Squadrons is 90 points, so that leaves you with 10 points to conversions to PS 4 EPT TIE/FO's. You could do 3 Omegas for simplicity and the initiative bid, or 2 Omegas and Zeta Ace.
I'd rather have this than 5x Crack Squadron, an Obsidian, and an Academy. And that placed top 16 at Worlds.
You gain all the benefits that the FO brings over the TIE, no drop in PS and only a loss of one ship compared to the Worlds Crack Squadron list.
Do you drop Zeta Ace for Howl with Crackshot?
