Hum interesting view...
Personally smaller breast won't be a deal breaker, as i recall i really flashed on Nikky(Talia MTLGFE now) at GG2 because how pretty she was facially and her cloathing/hair style was really fitting her well that night too. But it seem i usually go for bigger breast in general. Of course when you can see an SP facially before a meeting it help a lot, i would had not choose Nikky based on picture only... but when i saw her, bingo, had to see her. Then there is girls in the middle, like Hannah also formely at GG, she didn't had D cups, actually i think she was listed as Bs, but they where more like a generous C to me. They where not that huge, but very good shape, you really had a nice handfull grabbing them...
Of course i always been attracted to the pornstars/strippers with huge breast... because of my teen years, but i think if i tended to choose more SP with big breast in my early years (before the parties and such) its because i knew that if the face disapointed me a bit, at least i would enjoy the big breast...
Anyway its kinda like that lol. In recent years, the best big natural boobs i experienced was Vanessa at Lou's, wich sadly didn't stand around long enough. Her breast where really "stupendous" (Friday the 13th refference lol) big, generous, round, perfect nipple size... wow !!
But i also saw plenty of other girls with amazing natural breast. Jordan formely Eleganza now MTL GFE, Christina MTL Sex City, Hannah GG and of course Kate formerly GG now MTL Sex City. I also saw a nice number with fake ones. As eager said, yes Jessy from GG did had nice fake ones. She also explained to me that she used to be similar size but wanted them to be "firmer" or something... but she didn't enhanced much the size. Eve from GG has fake ones but they are not "big" , she is so "petite" that they look bigger on her, but in truth they are not that big, but they fit very well on her and are nicely done.
In any case, personally i can say i like anything from B to DD, it always depend on the shape, size of the nipple and such... how i like them. But A is really too small... of course if the girl has a perfect little ass, super pretty face and such, it won't bother me too much, but i like to have somethin to grab...
But when it comes to SP i realized over the years the breast are not the main focus unlike strippers... sure its fun to grab them while in cowgirl but you don't spend the hour touching them, unlike a stripper where i used to spend much of the dances on the breast... so i would usually take upstairs only girls with generous breast.
