WW requires forearm pronation, internal shoulder rotation and that is not necessarily the result of simply swinging low to high.
I agree, it’s the result of you naturally wrapping your arm across your body on the follow thru.
Listen, you can try to slap the ball by firing your forearm or wrist and spank the moment of contact with an early WW swing. But unless your Jack Sock
It’s just going to lead to a wildly inconsistent FH.
What happens is the wrist snap and forearm turn prior to contact changes the angle of your racket face before and during contact with the ball. Every little degree of change causes a massive difference in launch angle and accuracy. Your FH will launch too high sending the ball long or launch to low hitting the net. For every time that happens you’ll spank a FH where the stars align and the angle is perfect and the snap adds more topspin. But unless your Jack Sock and you’ve hit like that for 5 hours a day all your life you won’t control it at a level that allows you to play consoistent Tennis. You’ll just have a wild FH. TTW has had many threads discussing this point.
@mad dog1 correctly calls it a rabbit hole for a reason. Can it produce awesome shots? Yup. Will you nuke a gorgeous FH once in a while and say, “wow this is great!” Yup. Will you also triple your Unforced Errors and mess up your current FH? Yup.
I literally just clawed out of the rabbit hole after wasting 2 years buying new rackets, trying different string, thinking I wasn’t snapping hard enough at contact to keep the ball down, thinking I needed to close my racket face more, thinking I needed to switch FH grips, practicing so many FHs I gave myself tennis elbow... complete dead end rabbit hole. All while my simple, clean, low to high 2HBH was at 4.0 level.
If you still don’t believe me watch this vid and repeated pause and go frame by frame. You’ll see that Fed doesn’t turn his wrist AT ALL until the ball has already left the racket:
