Hey mate, nice swings! Couple of things I'd point out particularly referred to wall practice, being an experinced adept:
- Don't you have issues with balls flying long on the court? It seems to me you lack some spin while sending the ball with rather healthy (and sometimes clearly excessive) height over the net ... line?
The wall doesn't give enough feedback on that unless you're very focused and aware to control the ball shape. You might need to either hit lower, or get your racquet more closed by contact:
If you don't want to mess up with the grip going full SW, try executing more pronounced racquet head upward rotation as you drive through the ball, to achieve this type of racquet orientation at contact:
Get used to more spinny feel at contact and more shaped ball trajectory.
- Another thing is how you finish and prep for the next shot, which is affected with wall returning the ball twice as soon as a player from the opposite side. You don't fully follow-through into here (shoulder coming forwrad) on many shots:
Although they might speculate it's after contact, freezing your body hinders the flow and spoils the swing. I believe you can actually do it properly, there are some good finishes in the vids - it's mostly the wall timing throwing you off.
Even though you cut full finish and recovery from your sequence, you are still rushed preparing new shot - it's too brief. You'd better start earlier, keep off-arm on the throat longer, and then flow into new shot. Well, the wall timing again...
What I suggest, apart from on-court practicing, is altering your wall hititng if you work on the techniques:
- Use drop feeds and hit shots 1-in-a row, but with full prep and finish.
- Use underspin feeds off the wall, then hit 1 drive shot, catch the ball and repeat.
- Alter FH CC drive with BH chip to reestablish the FH ball. Mirror for BH.
- Get farther away, hit more balls on descend - rush initial prep, then go all the way through and into finish with more time than you have camping on the line. You can even introduce yourself for some 2-bouncers hits - they are much closer timing-wise to on-court hitting.
