Heavy Cruisers and even Carriers are best on the flanks as Horns, since all their firepower is broadside. And they can pack an assault punch when they cut in to the middle of the enemy.
R&D crusiers and Anything with Turrets are fine up the middle, as well as the Frigates. You want to make the most of that reinforced fore, before the real scrum starts, and the turrets come into play.
If the enemy disperses, its perfect since with little limiting LOS, you can always find a target inthe key range Band.
If the enemy clusters up, that lends itself to nice combined attacks, shooting one ship with torps, one with turrets, and boarding the third. But mainly, they'll be evry vulnerable to the horns doing the pincer thing.
