I still say, SMASH THE GRANNY OUT OF IT.
praguetaz, if you are only really going to play a 'normal' innings, then a normal field to you will be effective. Get a genuine pace bowler to bowl full and at off stump or just outside off, Set up a ring field, 3rd man and probably either long off or deep extra. Will let you make your own mistakes when you are trying to play over the top or go for the legside when you get 'bogged' down playing normal style cricket in a short format.
