I would say that the best two cordons I would have seen is Taylor, Waugh and Warne and lara, Hooper and Richardson.
Apart from those two groups Lloyd, Ponting and Greg Chappell were also special and Dravid and Hayden were exceptional to spin.
From days gone bye we are told that Simpson, Hammond, Everton Weekes and Sobers were exceptional along with the south african trio of Bruce Mitchell, Trevor Goddard and Eddie Barlow.
Speaking of South Africans their current trio of Smith, Kallis and De Villiers is exceptional as well and the best today.
Flintoff, Botham and Greig all added slip catching to their other all round contributions and the West Indies of the 70's, 80's would not have been as complete with out Lloyd, Richards and Greenide in death row next to.Murray/Dujon and likewise for the 2000's Australians with out Warne, Ponting and Langer.
