Over the past week I've been mostly focused on the basics of BH and FH loop. I realized that I can't just stop practicing FH and expect the new form to stick, so I did a good amount of FH practice this week with my training partner. I basically did a condensed version of my entire learning process, focusing on one portion of the body at a time from the ground up: legs/hips, core, arm, then wrist/racket angle, hitting first, then looping, and lastly focusing more on footwork.
For the BH, I was stuck a bit in how to hit into the racket more. I mean, I can hit it, but unlike the FH side I couldn't easily add brushing to the hit and more importantly, I didn't get the feeling of holding and slinging the ball. Whether hitting or brushing, contact always felt short. I think by the end I was able to do better. I think the issue was I was too focused on keeping the elbow stable and using external rotation to generate power that I forgot the forearm extension and supination part of the stroke. Without the extension my stroke was very left-to-right and not enough forward, and without supination I couldn't effectively hit into the rubber/blade. By the end of the training it felt good, but I'll need to be able to replicate it for an entire session before I can call it a success.
I also did some limit testing re: my newly added technique of bringing the racket back along with the ball. I wanted to see just how little of it I can do while still ensuring good synergy and relaxation before hitting the ball. Turns out I can use very little of it, I just need to do it right before the ball arrives at me. Essentially I'd think of the BH stroke not as starting with the forward movement, but starting with a bit of backward movement before snapping forward. It can be pretty subtle, which is probably why it's very hard to tell on video.
I also tried out my Viscaria with T05FX on the BH side. It was sooooo much easier to hit into the rubber, with whatever crap technique I could do it. Every shot generated the characteristic Tenergy pop and sound, every shot felt good, and they had fantastic land rate. Q968 with D09c generated better quality, but it was much, much more unforgiving. That's really one of my issues re: people suggesting using easier to use equipment. If you're someone like me who doesn't really care about missing shots and care far more about improving, something like the Vis/T05FX can really do you a great disservice because it just doesn't let you know when you're using the wrong technique. My BH technique is now good enough that even my coach thinks it looks fine, but I know something is still off because my equipment tells me so.
