What drills to you tend to use in practice?
When I'm coaching I use the regular X pattern (deep forehand, short forehand, deep backhand, short backhand) a lot along with one called Approach and Volley or a variation of it Approach and 2 Volleys the most as well as a few hand fed drills depending on the person I'm coaching. They are in this video...

The one right at the start at the video, first few seconds is also great and can be done with a racket in hand like Pato is doing or hand fed. Again depends on the skill level of the individual you are coaching.
He's making him move back, and starting in front of the bucket but you can reverse it and make the player start behind the bucket and make them move forward.
Also, the ones I love a lot are the hitting the ball straight down, getting an awkward bounce and having the player adjust and move their feet up and back, side to side to learn how to get into position. Tough drill, you can see it done starting at 10secs into the video, hitting the ball straight into the court, then bumping up a short one so the player has to move forward, etc. Killer drill, and great on the footwork and strokes. They do it with overheads from the baseline as well you can see.
Just be careful you keep the player in control and they are still within their limit, then slowly over time as they get more comfortable and learn to move better, start increasing the intensity and difficulty of the drills. Last thing you want is them to develop bad habits and have them flailing around like a windmill cause they can't keep up.
Which Yonex are you using?
Yonex RDiS 100 Mid
If I might ask, are you a counter-puncher?
I'm 6'4, counter-punching isn't be the best tactic for me.
Are you using a continental grip on the BH side?
It's slightly closed, if I'd stick my arm out and look at it head on I'd be pointing around 1 o'clock or so with the top of the frame (hope that makes sense) but the grip varies slightly depending on the ball. Contact higher up around shoulder level I'll close it a tad more. My slice grip is continental.
I never noticed my racket being kinda open like that on take back, djokovicfan mentioned it also. Maybe its just the camera angle from the back, the camera was somewhat close cause it looks normal to me from the second angle taken head on. I guess its just the way I bring the racket back, I dunno sub conscious I guess
