IMO any team that goes to the sub-continent with only 1 spinner is asking for trouble - big time!
you also need your seam bowlers to have something extra - pace / bounce to make up for the lack of help from the pitches, and to distinuish themselves from military medium pace that could become cannon fodder. I also think that you do need someone of medium pace who is physically strong to take on extended workloads & who is also accurate - not so much a 'strike' bowler.
So fas as player's ages goes - the Aussies have proven this to be hogwash - Hayden, Langer & Martyn all got their current test careers back on track / lifelines in their late 20's - early 30's. Even Richardson could be called a late bloomer! If the player is the best current option to do the job, especially if it's in a specialist role, then they should be picked until they either become unavailable or some more / better options are found!
I have a sneaking suspicion that a lot will depend on discussions with Sneddon, Fleming & the Selectors as to where NZ cricket goes from here - do they start to rebuild with a view to 2007 now, or do they go into damage control with the squad & talent they have but rework the lineups & tactics?
I would not be surprised if we see Adams, Astle, McMillan & Vincent given a break from SL. Cairns can no longer be considered part of the NZ test squad until further notice because of his recurring injury probs. Although Harris got a break re the WC he had not figured in Test selections since the WI & I would be surprised to see him included in the Test Squad.
my Test squad
Horne
Richardson
Sinclair
Fleming
Styris
McIntosh
Hart
Vettori
Bond
Butler
O'Connor
Tuffey
Oram
and another spinner
Tuffey is a question mark re subbing him for another new batsman.
ODI squad:
depends on form of the above - esp the bowlers, but Hitchcock to be included
