>do they feel different from a breastplate to not just use that?

They're definitely not as good because they're loose which causes a bunch of problems. They're also latex bags full of water, and there's a risk of bursting obviously. The only reason I use them is to play around with different sizes (and air is TERRIBLE for that) and because they're cheap. My only breastplate is a Roanyer Z-cup inflatable which is fun when I want to be huge but lately I'm a lot happier with sizes somewhere between a European M and S cup and I don't have other plates in those sizes, but after playing with these I think I will order a Roanyer S-Cup East-West shape.

I have a set of balloons that I have filled to around 4,500 cc's and literally just an hour ago filled some to about 5,500 cc's or so which is a lot closer to what I'm after. They're also really damn heavy (fun fact, water and real breast tissue and implants all have about the same density, so a 5,500 cc water balloon is pretty close in weight to what a 5,500 cc implant would be), and I'm not that keen on weight even if the jiggle and sag of them is nice.

Because of how big I like them you either can't find silicone plates that big (e.g., Z cup) and if you go by Madzisstacked's advice silicone plates suck because they leak oil like crazy anyway so if you're after weight, it's easy to modify them a bit and add e.g., a water balloon or half a balloon and the cotton stuffing after.

>also a good idea, is there a known limit to fat transfers is why you say?

For a good idea of "limits" go look up Demora Avarice. She has done fat transfers for most of her augmentations (and is HUGE) but recently had to have some expanders put in as part of an internal bra. As with implants the limit is probably your own body and whatever the doctor is willing to do; unlike implants though you don't have to have them manufactured.
