I was thinking about this lately and there are many good YT tennis reviewers but what is most important is to take those information depending on your own style and level.
Like if Luca from R&R is crazy enthusiastic about certain type of frame, it is because it suits his game which is on a very good level when compared to us here around (at least that´s my impression).
When you play like him and are on his level, than great for you - but for me it means that it might be too much of a racquet for myself
