My plan with the breast morphs was to do a basic one for size that looks reasonably organic - not screaming silicone, but not necessarily representative of the average large natural breast - and have separate ones for sag, areola size and so on. Also I've set myself the challenge to make a morph that works at a large range both negative and positive, which really helps me identify problems, but also limits the possible shapes a little bit. If I make them sag realistically at strength 3, I'd have to lift them up a bit more than I'd like at strength -1, a.k.a. flat chested. The ones posted above are still way too bulgy at the top and sides, which I've fixed in the meantime.
