I tend to go with the most obscure ones (as well as well known).
My #1, 2 and 3 (the rest follows)
Stephanie Renee, aka Stefanie Renee. (she did 10 porns.. and has a 10 Body, and its natural). She is ridiculously gorgeous. She doesn't do porn anymore.. and it will probably haunt her for the rest of her professional career.. lets hope she comes back.
Lily French Aka Roxy Hart/Heart. Her facial expressions are priceless. Definetly not the hottest girl (she's very slim).. but she orgasms so much... (she ain't a squirter though). Something about her just gets to me... it might be cause she's french.
Gwen Jade (Gwenevieve). She's cute.. and (imo) has an amazing ass. She's slowely doing more porno's though most people don't review her very highly. She has me at her looks, and her voice.
Brittny Blew (yea thats her name). She's just starting.. but DAMN!!! She has a myspace page, has done at least 2 porno's, and will continue to do more. Its her personality which really gets you wrapped in.. cause she's SHY.... and she pulls it off MAGNIFICENTLY.
Szilvia Lauren. She has to be pushing near 40, but what a gal.. Need something european.. her and the one below are a pair of the best.
Simony Diamond, aka Simona. She just likes it in any hole she can get it in. She moans the exact same way in every movie she's in.. but a nice DP chick, if that works for ya.
Lily. She hasn't done much.. but I've never seen a chick so small take something so big... for so long... EVER... I swear she's in pure agony after a while. Check the bangbros site, she did at least 3 with them. Mega Cute, Short, and Tiny (The perfect Kind of TINY, Great Ass, Great Chest, Perfect Waist).
Dasha She's retired... lord I wish she wasn't though. She's the kind of woman you could only hope to marry, and just ravage repeatedly every night. She's the kind of girl you'd lose your job to because of excessive lateness of absence (cause your fking her so much). She had two phases, her early stuff, and her late stuff. The Early Stuff is GARBAGE, so if your watch something with her in it and its booring, its her early stuff, her later stuff though... Your eye's may rupture cause your brain exploded due to the amazement of her work.
Jenna Haze. She's one of the top 5 in porn I'd consider. She's kinda over the top with the voice acting (her and Charmaine star just never sound genuine), but if you just want to watch someone who constantly calls her a slut and wants you to fk her.. she's probably NUMERO UNO.
Kobe Tai. Get her stuff if you can find it. You'll never look back... and you'll pretty much base every Asian Pornstar off of her performances (none so far have measured up).
