I wouldn`t RE chlor. It is quite expensive so you cant get high in the ranks with it. I would rather RE the epidote to have another queen killer.
Lyth/Flysch/Epidote
As for the marauders pyth and pikes are must haves. For the last pick i would choose something with at least range 8 and energy or kinetic damage. Baracuda is a good choice.
When you do a setup like this you can spam 1-4 ships and have dummies that strafez cant do anything about at alle the rest of the positions..
Killing queens: Pike, Broadsword, epidote , (Baracuda)
Defending against queens: Pike, Broadsword, Sword, Epidote, Cronus, Borr, Baracuda.
