I guess I feel like elaborating. The blade and rubbers you have are fast fast fast. The rubbers you have are very grippy and very reactive to incoming spin. To use the rubbers, you kind of need to be quite good AT READING incoming spin and quite good at KNOWING HOW to touch the ball at an angle that will either let you use the incoming spin, or minimize the effects of incoming spin on the shot you will try and make.
In seeing the somewhat recent video of you playing vs that LP player, you are not really doing any of what would make that rubber and that blade a powerful combination. What you are doing instead is trying to hit all incoming balls really hard, while you are not quite set for them, and are therefore in a rush. Now, there is nothing wrong with this being the level you are playing at. You have made amazing improvements from the first video footage you posted to the most recent. The only reason the above information would be good for you to understand is, if what you are doing in any way resembles what I described above, you would be much better off with a setup that was notably easier for you to control.
Now, the equipment I described, when you are just banging the ball around and hitting topspin, it would not feel as sexy, as exciting or as fun to CRUSH the ball with. It would be slower. It would feel less alive. You would actually have to work harder to get the speed, but some of that harder work would need to be more precise contact.....sooooo.....TECHNIQUE. But that less sexy setup, it would actually also help you develop better technique.
At first, you may not like the setup. You may not want to use it. But, in the long run, if you use it, you will get better faster and start making the kinds of improvements that will allow you to handle varied spin, receive of serve, and some of the more complicated play styles that you are currently struggling with.
So you could think about backing the equipment off as an investment in your future development. But the changes that would help you have nothing to do with this idea that you are attaching to this term "throw angle" which BrokenBall rightly points out is not really so definable.
