A recent WC match made me think about something Glen Turner had expressed, that the one day game requires a 2 innings format. the match was between RSA & NZ the over head and pitch conditions contributed largely to the 1st stanza of the match and RSA score reflected the difficulties. I think Glen Turner is on to something here, in away it'll at less level out the effects of the conditions plus any decision made whether to bat or bowl that did mot give you satifactory results, giving both teams the ability to address their postion mid way through both diciplines.
instead of the per nrmal 50 over vs 50 overs, how about first 50 and 2nd 50 overs split between the teams 25 each. the not out batsmen from your first 25 overs will return to continue from your 2nd set of 25 overs.
