@tdotter and transmogrifier:
You both raise valid points.
It's probably worth remembering that our particular fetish is NOT the majority interest insofar as the mainstream adult entertainment industry goes... when awards are given, or sales records broken, more often than not it's going to be a model/actress who's not mentioned in this forum often if at all.
JMHO... but I think that Denise Davies, Tyra Moore and Larkin Love are all fairly well-known and popular among fans of larger, natural breasts in hardcore. To be sure, they're not as well known as some other performers, but not every one is going to be in the top tier as far as name recognition goes. AFAIK, all three of them are still working (though I don't recall seeing anything new from Denise in a bit) so their relative notoriety is still subject to change: they could become more well-known if they produce more great content and attract more eyeballs/enlarge their fanbase.
Again, I really am a fan of all three women: each one of them is a perfect example of what appeals to me personally: wonderfully pretty but blissfully non-generic, naturally large breasted, enthusiastic at hardcore and (most important) most of their work leaves them looking like actual real women, not over-processed, unerotic simalacrums of women.
