I agree they have too many angels, they really need to drop at least 4 of them (Lily, Stella, Martha and Sara can go)
But I don't think their problem is related to the models, I think it's their production team, their designers...
Seriously, they are all good models, Lais, Elsa, Jas, Taylor, Adri, Behati, Candice... they are all worth of their position, but they're not being properly used. VS became PINK. They seem to want to make the Angels to look younger than they really are, they're not intersted to sell to women anymore, wich is a big mistake.
Btw, Lais and Jas are shooting with Monica Cima. I didn't know her until now, but i was checking her IG and OMG: she's beautiful and looks amazing
