Her and Tiffany Towers are my two faves of the type of girl of that era. 
Pandora Peaks (Stephanie Schick) was never a draw for me... she just was too fake. I much prefer naturals over augmented. I went to look up Steph's stats, and realized that she didn't even start her adult entertainment career until she was 27 years old. She "retired" when she was 39, so only a 12 year run.
I was surprised to learn she only stands 5'-6" as she always looked much taller in images.
Her birthday is April 12, 1964. Seeing her more "natural" look, the brown hair and natural chest size, actually seemed more appealing.
That's the good thing at the world: there are different tastes and everyone will might find something that triggers their interest 
I like the round shape, but I am not focusing only on this, for me there are a lot more individual characteristics important.
I'm with you, full beats droopy, which many are (or will become) when braless. It is all a matter of taste. Implants impart a fullness often difficult for natural breasts to replicate, though not having actually seen the results of the European internal bra for naturally large breasts, may remedy that aspect; I have read they have proven to be quite popular since their introduction a dozen years ago.
But that is why we have a wide variety of threads here, to address many different tastes, even those who are not interested in breast expansion or even overly large breasts, which one would assume to be the subjects given the title of the site. The heart wants what the heart wants and there is no denying the fact.
Pandora just exhibited a body that one might assume would be the dream of any girl and had a look about her that was sensual. If it wasn't for Hollywood having a stick up their collective asses about boobs beyond a D cup, Pandora could easily have been a great star, not necessarily in the Marilyn Monroe glamor sort of way, but certainly in comedy movies and sitcoms, where the boobs just add to the character, not dictate the character.
