Progress report--
The Williams Hybrid is fruiting:
The Dwarf Cavendish just sent up a flag leaf (this DC is a pup of the DC that fruited earlier in my aquaponics system):
The Double is loaded with 16 leaves and looks like it'll be sending up a flag leaf at any time:
The Fake Ice Cream (actually a Namwah) looks like it's at a similar stage:
The Dwarf Namwah, Raja Puri, and Dwarf Orinoco all seem like they could throw up a flag at any time, too.
