Wish list: either one of Odoe / GATF / Brassy
Planning upgrade: either a double footprint tank or similar size depending whether the comm will succeed or not when this batch of small monsters hits 15 inches average.
I say don't go with gatf will require to large of a tank and a setup the rest will not like. Brassy I wouldn't try till you have he bigger tank. Odoe seems like the best option, but not many.
