One thing that wasn't addressed that I might recommend is that if possible, make all members be on the same FC, or at the very least share a LS that is not just the coil LS.

In my experience, players that alienate themselves so that their only contact with the static is raid time tend to become flaky or unreliable. Being in the same FC static members can do more things together and bond more easily. For example, my FC basically consists of 2 coil groups and some friends. We tend to do the few content that's doable outside a static together because we are all in the same FC. Treasure maps, raising gil for the house, Primals, etc. We not necessarily do things as the 8 core members, but it helps.

Also, I'd recommend that if possible, have Meat and Mead II (Food Buff) up every time your static is on raid time. It alleviates food costs greatly. You might also pop Back on your Feet if you feel like you can afford it to maximize success chances.
