Up-potting cocoa tree

I have 3 cocoa trees that have been growing for about a year in D60 Deepots (2.5" x 14"). I should have up-potted them long ago, but i’m finally getting around to it. I’m trying to decide what containers to put them into. I’ve been looking at putting them into TreePots - specifically the TP616 (6" x 16") or TP818 (8" x 18"). Does anyone have any suggestions?
