Lemme guess, Gat/Mortar?
Actually Merc/Mortar, all day every day (I used to fly exclusively flak/gat til the Heavy Clip nerf). I also always shoot a lot of fireballs when I play as Ryu in Street Fighter. It's just the way I play; with the full intention to win every match. I do that by utilizing what I view as the best attacks I have available to me (Mortar/Hadouken) as efficiently as possible.
I totally respect the fact that you use strange setups on your ship. It's why I love [Cake]. It's how you guys have fun. I have fun by doing everything I can to ensure a win. As long as we're both having fun, I don't see any problem if I, or anyone else, uses whatever the current most effective weapon pairing is 100% of the time.
My point is it's WAY easier to organize an unknown crew on a pyra than it is on other ships. Let me elaborate it with two examples:
Easy junker setup is: Gunner/buffer bottom deck, firing a piercing weapon (merc/gat) 99% of the time, tapping main engine 1% of the time. I suppose if you want to put a real long-range weapon on the front (I usually just use flare), he can do that before you reach engagement, too. Primary engineer on hull, and on hull only, with maybe the OCCASIONAL balloon tap. Secondary engineer watching the engines, balloon, and jumping on the explosive weapon (flak/mortar) only when it's time to get the kill.
It's ALMOST as easy as Pyramidion, as long as you have a good and dedicated engineer who doesn't mind spending the entire match tapping the hull, and one who doesn't mind doing quite a bit more. Honestly, I try to keep 1 engineer on the hull as close to 100% of the time as possible on any ship I fly (Mobula is the only exception).
