Natasha Zvereva is my personal favourite, because of her personality and exciting game.
But the best doubles player of all time has to be Martina Navratilova. I don't know the stats, but if you looked at them that's pretty obvious. And she's still playing well even now!
Others: Pam Shriver, Gigi Fernandez, Helena Sukova.
Of current doubles players, Lisa & Rennae are the most consistent, but I have to say that the most talented doubles teams and the most enjoyable to watch are Black/Likhovseva, Hingis/Kournikova, Williams/Williams. Also Davenport/Morariu but obviously Morariu is no longer playing.
Other great current doubles players would be Aranxta Sanchez-Vicario & Ai Sugiyama.
I think Lindsay's Olympic title is in singles (96) and not in doubles? Arantxa has two Olympic medals in doubles too (silver in 92 and bronze in 96) + 5 Fed Cup titles, I think Arantxa and Conchita together hold the record for more victories in doubles in the Fed Cup, with a record of 18-3, going undefeated since 1989, when they lost vs. USA (Garrison/Shriver).
