If the fields for S2 are the same as S1 (150ish) then I think playing down to the cash places is a good idea. The problem is that Apat have been hinting that S2 will be a lot bigger, venues and comps it seems.
With fields of hopefully 250+ for S2 it wont be possible to play down to the money, so were do you draw the line. Time, say a midnight finish, or numbers 30,40, 50 which will mean a later finish on the Sunday. Im sure those in charge welcome our comments but there may well be a price to pay for larger fields in S2.
