The serves would still be incredibly effective, but not tennis armageddon like some seem to think.
No old strings. Modern racquets on old surfaces- if they didn´t slowed down surfaces. I think you meant my coment one of those.
With faster surfaces, like old grass, indoor carpet and faster outdoor HC, Isner, Raonic or Karlovic-2007 would have more aces- don´t know how many more, but more, but other things will be more too - like service winners, unreturnable serves and easy points like 1 groundstroke, volley to win point after big serve. Because of lower bounce or faster court, there would be less reaction time on return. I don´t know how about rallies, simply there won´t be this super long rallies lke Rafa-Nole, but 1st serves and service games hold i am sure that decent servers would have big server´s stats and big servers would have better stats like nowadays.
