I think grass is grass. It’s still going to skid and bounce lower on that surface compared to HC or clay.
Was 90s grass faster? Possibly. But it also wore faster (which is why they changed the seed around the new millenium) and caused more unpredictable bounces.
A bigger cause for S&V to decline was poly string, not the grass itself. Now Im a fan of aggressive/attacking tennis myself but I don’t buy that 90s grass players were better.
(By the way the slowdown is real and is most prominent on HC not grass)
