I am not qualified to write any review but just from the point of view from an adult beginner, let me say this:
I just received the FM CF bow last evening. It came in perfect time, just before my practice and class, so that my teacher could also listen to it. First of all, when I unpacked it, rosined up for 5 minutes and started playing, it didn't sound well. Actually I could hear almost the same or little bit less dynamic tone than my crappy old bow. I thought what the h***! Then I stopped playing.
I just put my violin down and looked at the bow. It is different! It is slightly lighter, has bit more hair, perfectly shaped without any twist. The frog is beautiful and not moving unlike my old bow. I thought I should feel it first. I just did hold the bow like a conductor baton and started to move it in the air humming some songs. Yes, now I am getting a feel of it, it's weight, angle and pattern. After few minutes I cleaned it (thanks FM for including the FS cloth, its awsome!) and this time rosined it up for 10 minutes with mild strokes. Took my violin and gently stroked it, wow! It sounded better. I played for 30 minutes and each few minutes I could feel the bow is getting better in my hands or I was growing with it. It was a matter of getting used to it, from a crappy twisted unbalanced bow to this beautiful one. By the time my class started I was feeling perfectly comfortable with it. No need to say my teacher also liked it very much.
As little I know, I would happily recommend it. I got the one with the treble clef on the frog and it is a beauty to look at it too :).
A table, a chair, a glass of wine, a bowl of fruits, a music system with lots of records and my violin. What more I want to retire?
