I'm curious what the final result ended up being. If it was hiding somewhere in your post, I apologize for missing it.
My guess if you've got Intel Sweep tokens on the map. Which ship is the Intel Sweeper? And it doesn't look to me like any ship is particularly well positioned to pick up the tokens. That's one objective that if I take it, I always aim to pick up the points. There's an odd number of tokens, and second player ought to have positioning. The opponent either concedes a 7-4 minimally, or they are forced to come to your position. That by itself can be a difference-maker in whether you get double arcs.
The biggest thing I see is that you want more of a 1-2 punch with those MC30s. MC30s get 1 or maybe 2 good attacks off in a game. Its ok if those occur in a sequence. Its very difficult to get them off in the same turn, though it might be possible with that ISD if you've got one trailing and the ISD is forced to activate and come into black range of both of them.
I'd probably fly more head-on with it and just eat a shot, as Ard discussed above. You have to know exactly whether you can eat the shot or not. That's where his chart is useful. With an MC30 set-up like that, you are absolutely gunning to drop that ISD. Now, I've been running a one-MC30 list, and getting it set-up on a double-arc and then zooming off while other ships pummel that ISD is often enough. I'd think two double-arc shots in sequence really ought to drop it to the point that one good MC80 blast would finish it.
So basically, you can and should fly them more aggressively. For that matter, you can possibly look at putting them both in threat range, and if he activates and kills one, the other can open up on him. I'd personally rather go for the 10, which is threatened by this kind of play, but its perfectly doable to ensure you do get a double-arc drop on that ISD. From there, your Ackbar-Defiance finishes him off.
Does that help? I'm sure Gink and Ard will also add helpful suggestions.
Oh I posted the results on another thread, my bad. I won 8-3. The MC80 was the intel ship and ended up picking 2 tokens. The ISD picked one that I was about to grab, but him activating first again let him have it. In the end, we both had 2 tokens. A bit of misplay from our parts because we rarely play this objective (first time for both of us).
The MC30s were ackbar MC30s, so ATPs weren't on the ships as I was not going for double arcs anyway. I too feel I should have been more balsy with the ships. Being overcautious ended up making the ISD survive as the MC80 did a number on him at the last 2 turns.
He only destroyed 2 A-Wings. He got a bit unlucky with his rolls. I destroyed Demo, 1 Gozanti with BCC, Rhymer, 4 Tie-Bombers, 2 TIE Advanced, Intel ship (the 4 A-Wings really paid off)
