Best cricket captain in the game?

I was watching South Africa versus New Zealand in the T20 World Cup and it got me thinking about who the best captains in world cricket are at the moment.

I think one of the things about a good captain is that sometimes their skills and attributes are overshadowed by the quality of the players in their team.

Here was the list I came up with and would be curious to get feedback from our readers:

Daniel Vettori: The New Zealand captain is without question one of the most astute players in the game. He's never really had a quality team underneath him but he has made the most of the opportunities when they have presented themselves and in ODI and T20 cricket, Vettori has been surprisingly competitive.

Ricky Ponting: "Punter" inherited a top quality team but it is not easy to make a quality side "gel" and become one of the most successful units in world cricket for the better part of a decade. His competitive nature and his never say die attitude make him one of the best in the world.

Graeme Smith: Is Smith a good captain? This is one the questions that rolls around in my head regularly. There is no question he is an awesome cricketer and the kind of guy you would want in your corner in almost every fight. But is he tactically astute and can he think on his feet in the way that somebody like Johan Botha (his deputy / stand-in ODI captain) can?

Forget the whole "chokers" tage which gets bandied around. Every now and then I get the sense that Smith "innovates" for the wrong reasons or doesn't know how to change the gameplan when things are looking questionable.

Dunno - thoughts on who the best current captains are in world cricket and who are the more tactically astute players we should be watching in the next few years?
