Cracken gets left out to dry and is the only ship that your opponent will be able to get a shot at after Jake and Tycho unload. The thought behind HU is to insure that Craken does what he needs to do before he blows up. I would advise running it with HU first a time or two, then seeing where you want to make changes to the list.
The list went 4-0 and was frustrating as hell to play against. I was flying Jonus with two HLC Deltas against this list. Jonus had Determination and HU on him. First exchange, he blows up Jonus. My Delta's took out Craken, but then never managed to land a hit on the A-wings. The list's creator is one heck of a pilot to boot.
I guess the art of this list to ensure Cracken being in Range 1 to either/both A-Wings, without any of them being in a direct jousting situation...
