cheers - I'd since read up. Longer rallies and endurance. Surprises me at the French how still there's very few breaks of serve yet within 2 or 3 strokes of the rally starting you'd think it wouldn't matter.

Am I alone in being a big fan of the tennis played at Wimbledon from mid 80s when it was BOOM, BOOM and move in for the volley. I'm certain in one final in the Sampras era (might have been against Rafter the Shafter) the longest rally was about 4 strokes.

Australian open was played on grass till 1987, never knew that

US Open was played on grass till 74, then clay for 3 years till hard court came in
