I don't really like it either. Its too stop-start and it stops the batsman momentum. Queensland were going along really nicely after their first 20 overs, but when it came into the second stage as its called, they completley lost their momentum..although to their credit the Vics did bowl well.
The WA NSW game is getting a bit tighter now, seems again that split innings format seems to be disrupting the batting's sides momentum, though as the players get used to this format I suppose that momentum shouldn't be so much of a problem.
