Basicaly my short and to the point points
1.ATP forehand is a superior technique and has the most bang for the buck in terms of spin and pace
2.harder timing and all that crap is bullsh#t, you dont control timing of the flip, its impossible, you get timing by feel, by hitting thousands of balls upon balls.
Serve pronation happens even faster, why is nobody ever questioning that? That its impossible to aim the serve because pronation and angle of racquet flips around so fast?
Because its not impossible, it takes hitting 100000000000000 balls and you build the timing by feel
Basically this. The supposed "easier timing" of the WTA forehand is just bulsh*t invented by some teachers who themselves are unable to hit a modern forehand properly. You can not teach something that you're not able to do, so obvioulsy it's easier for these teachers to say "I'm teaching the WTA forehand because it's the better forehand" than to say "I'm teaching the WTA forehand because it's the only forehand I know".
Tennis is all about taking time away from the opponent. The ATP forehand takes less time to prepare without any tradeoff when it comes to power and topspin, it's the superior shot and it's not even close. There's a reason why Serena Williams has dominated the WTA tour for so long, most women can't handle the speed of her shots with their prolonged take-backs. And it's no coincidence that women who had great ATP forehands like Henin and Dementieva found a lot of success against S. Williams when most other female players failed to do so.
