Re: what does the Grandslams need to improve for the future?
Definitely reduce the number of seeds to 16 although I would keep a 128 field.
No need to change the surfaces - there's room for all four.
Whenever the roof is finished at Wimbledon - if it rains then matches of a later round including high ranked players should not be played on Centre Court ahead of unplayed ones in a previous round.
Agree the A/O should be put back to Feb/Mar and there should be at least one extra week between RG and Wimby.
Each one has it's own characteristics - I wouldn't really change them. I personally don't like the showbiz style of USO and the match scheduling but then many do.
Margaret Thatcher - Michele Bachmann two strong women of our time.
