Too early to call as yet. Clarke has scored most times that we have really needed him to - especially in India. Strauss is in a different position in the batting order. A lot of water will go under the bridge before a call can be made on this one.
Very different batting at 6 for Australia when it is four or five sessions before he gets a bat in most situations.
I haven't seen much of Strauss except for a few glimpes on fox - he has definately improved the Pomms though and seems pretty consistant at the top of the order. Maybe in a similar style to Hayden ie attacking opening bat.
At the moment Strauss is ahead...Although they wont go head to head as such it will be a good contest for the Ashes....I predict that by then a more seasoned Clarke will take England by storm. Leading run scorer on tour.......... The Aussies will work Strauss out early and he may struggle a bit.....
Big call wheel against Polluck and Ntini, SA is let down by there 3rd and 4th bowlers compared to us.
As for Strauss, well i saw him play for an hour yesterday and he was good. Very good head on him, picks the right balls, fantastic footwork - everything you want. I think he has clarke by a bit, mostly on maturity, but that counts for a lot.
