Haven't been playing at all recently (2 weeks? I don't know anymore), because teachers tend to create project due dates(for a presentation, a film, a portfolio, a paper, and a software development project) around the same time at the end of the year

I'm still alive, so it's fine.
I plan to practice with my family and friends on Thursday (no school).
I'm probably going to warm up my forehand with my sister, and then try to work on backhand shots, since I'm lacking a little bit of speed there. It'll most be flipping and the following shots (I'll probably end up looking like big bully, though). I'll have my brother do some serve and attack with me. Hopefully, he won't get frustrated. I'll try to get him to start doing down the line shots, since I've noticed that he's too predictable. He'll have to start aiming
the smash - loop hybrid shot or loop drive or however you call it is really a good idea , it feels sweet when you get it on especially on a backspin ball. However, the catch is that the timing is very critical , compared to a regular pure topspin where the rubber comes into play more. What I have experienced is it needs some adjustment when you change your setup , even when you switch from your older to newer rubbers. I saw your video and your timing was definitely on that day, I saw you do a similar crunch a couple of balls later as well . Faster blade might help more but you might need even more accurate timing
I've been doing the fast loop/loop drive thingy for a long time. In Mandarin, loop-driving the ball is called 'chong qiu',

, or 'rush ball.' (Chinese has way more specific terminology and words for these shots. You'd be surprised.)
At higher levels, a slow loop, especially one that is high, becomes just as vulnerable as a push. So yes, it is a very good idea.
Any shot that has a lot of speed has a much smaller margin of error(backswing, timing, contact, follow through, etc).
This kind of shot is really easy to overshoot, so you'd have to just practice.
However, it is really hard to practice this, because in order to do this consistently, you'd almost always have to hit the top of the bounce, and unless you are super-hyper-aggressive, you aren't going to be able to both get the timing, speed, and the swing necessary for the shot consistently. It'll will happen once it a while, and you'll see chances for this sometimes, but if you want it to happen all the time, you'd have to go coocoo for cocoa puffs.
