Yeah, old spent rhizomes work great and if you look at the rhizome as a source of stored nutrients or energy, the larger the rhizome the more pups it can produce. But the larger the rhizome the more crowded it will get and that increases the difficulty when separating. The reality is most sizes work great and once someone gets some experience they'll have more plants than they'll ever want. Last weekend I did a few hundred spent Florida rhizomes and that can yield a few hundred thousand new variegated pups. This weekend I've been working with the variegated dwarf Pisang Awak types which normally will have a lower yield, but still will produce a lot more than I want. Basically use anything you want, it'll all work.
First 2 photos are of macropropagating a 2" plant.
The photo below is a spent variegated Florida rhizome cleaned and ready for macropropagation.
