Good points! But as to this:
"tall players also tend to getting more tired in rallies than mid-sized players.
my main concern with the higher net is that it may lessen that last aspect."
It may be true of current players, but in a long run, literally, your argument is not valid. I believe that you understand!
i meant
by making rallying relatively harder for mid-sized players.
you said that the effect on the rallies would be small, but would that still be the case at top 50 level?
net play on the whole would become harder as the defender would get more time. that includes drop shots and even slices, while the latter would cause the tall players fewer problems again.
therefore it would become harder to move tall players around.
shorter balls and hitting from inside the court (inclusive applying power) would become relatively easier for taller players due to their strike zone advantage.
fore baseline exchanges the effect of the higher net would be smallest, at least nominally, but would keeping the tall player at the baseline be enough? they have greater reach and are getting better and better at lateral movement nowadays.
they are actually also better at applying power even from the baseline, but with that the higher net would indeed help, i guess.
i think that higher net would foster top spin baseline tennis even further.
it would have helped a topspin monster like Nadal against Soderling at RG, but i doubt it would help many players against Zverev et al on hardcourt.
