I just bought my third barracks and was wondering how everyone else organizes their barracks.
At the moment I have my main barrack with just the initial copies of all units and one or two copies that I may use (114/236), second is filled w/ fodder (iron&bronze) (213/250), and third with silver fodder and fairies/tin cans (184/250).

I needed the third so I could empty my presents which are currently at 87 but I don't even have room for all of them.

I know it may be weird that I have 213 iron-bronze fodder and that's causing my big storage problem but I like to save them up to quickly lvl new units. I used this to AW Noel the day I got her. It also only took a week or two to fully lvl/AW/lvl Spica and Mikoto when I got them. In the next few days I plan to use this stockpile to CC aria copies for lvling her skill.

So how do you organize your units? I'm a free player so I imagine Dolphins and Whales may have some storage troubles.
