I dunno, adding wings to mine (even as a sometimes-thing) is a decision that I'm very happy to have made.

I don't generally use mine much, though, unless they're in place of my arms. I mean, they do nice things for my silhouette, kinda, but they also often have to get left off for the demands of a piece.

The hyper butt permanently might not be wise, if at least because that's going to cause bleed over into any clean art that the artist might not be okay with. That, and if it's always hyper, it'll take so much more to get the hyper butt high in the future. :p

"help! my butt absorbed my wings!"

Not like I was going to fly with this much weight anyhow, so it could be worse?

Turn into an inflatable, now you'll be able to fly with those wings.

But are the wings too puffy to be aerodynamic...

Make your wings like mine, rubbery and functional even when puffed up.
