Honestly, Lambda's only hard turn is a 2 red. I dont think this list would be very good. as soon as I see this list, I would deploy on both extreme wings. Then full forward and I am at range 1 on turn 3 with you only getting 1 shot with each ship. at that point a lambda dies each turn as you concentrate fire. HLC is not that good for its cost. 7 pts is horrible. Half the cost of a full ship. I would much prefer having more ships. Hey dont get me wrong, I like my lambda, but it doesnt have the manueverbilty to use that firepower and with only 1 AG, it is dead in a turn or two max.
give it a try, but against a competent list, i think they will fail badly.
