The inaugural event takes place in South Africa in September and Giles says the selectors should pick county experts in their 15 on Monday.

The England spinner told BBC Sport: "We should think of players like Darren Maddy, Jeremy Snape, Mal Loye and Tim Ambrose.

"We play a lot of Twenty20 at county level and have specialists."

Batsmen Loye and Maddy along with spinner Snape are all in the provisional squad of 30 but Warwickshire wicket-keeper/batsman Ambrose is not, despite being the third highest run-scorer in the competition this season.

The 34-year-old Loye, who lines up for Lancashire in the finals of the domestic Twenty20 Cup on Saturday, played in the one-day series victory in Australia but was left out of the World Cup squad.

Warwickshire captain Maddy, 33, played the last of his eight one-day games and three Tests seven years ago but helped Leicestershire to Twenty20 Cup glory on 2004 and 2006.

Snape, 34, played alongside Maddy in Leicestershire's two triumphs, has featured in 10 one-day internationals and was part of England's coaching set-up at the World Cup.

Giles believes experienced players such as these could bring vital know-how to England's team in South Africa.

England's Test and one-day players have limited experience of Twenty20 cricket because their international commitments prevent them playing regularly in the domestic tournament.

Giles, who may be forced to retire from the game because of a persistent knee injury, added: "I would treat the game now with the respect it deserves.

"You are talking about a World Cup. We've not been blessed with winning too many one-day trophies so we should go there looking to win.

"There's no point us going there not looking to win it."

England won their first Twenty20 international, against Australia, by 100 runs in 2005, but were defeated in their next four matches before scraping past West Indies at The Oval in June.

Giles, 34, played 62 one-day internationals for England but believes the 50-over-a-side format might be outdated.

He said: "You don't see many 50-over games that go to the death, and Twenty20 cricket can turn in an over.

"So actually you might learn more discipline from Twenty20 cricket, because every ball, every over you have to be totally focused otherwise you could lose the game."

And Giles said Adil Rashid, the 19-year-old Yorkshire leg-spinner who has made such a big impression with ball and bat, could be picked for Test tour of Sri Lanka -- where England may take two extra spinners along with Monty Panesar.

But he also added that the tour at the end of the year was "maybe just a bit too early" for Rashid, a player he is "really impressed with".
