I like the idea of a bag of holding because it is a bag with an opening to put things in. With a ring there is no opening to put things in or pull things out of. It doesn't even try to make sense, and I hope Aleron never uses it. I would rather he get that pocket/door Hisako has when she got the star map out. The only time I would like a ring of holding is for a singular item, like a blade or wand. But that is pushing it, and as I type this I don't like it anymore.
