I'm not someone who has tried alot of rosins, in fact I've only ever tried 2 rosins- the new sartory rosin I got which is an upgrade from my first rosin that I got for free from buying my violin. After trying the sartory rosin, I have heard a big difference in the sound my violin produces but this might be due to the fact that I was using cheap rosin before... Sartory Rosin offers a strong grip in my opinion and the sound produced on my violin has a heavier and richer tone, which is why I feel that it isn't really my cup of tea because my violin already has a very rich dark ,mellow and warm tone and adding more richness to the tone has made its sound rather heavy-duty which also isn't a bad thing if that's what you would prefer. Judging from the fact that this is my first good quality rosin, I'm not really in a position to reccomend or state that this is a good one, but based on what I have felt from playing it, I can say that this rosin really suits people who wants to achieve a richer, more powerful tone and people who prefers a stronger grip on the bow. I had a great overall experience. I am getting more curious about the world of rosins after trying this one, I guess I just need some time to get used to this rosin and I'll probably like it more after my first month with this rosin. I hope this has helped some people in choosing their rosin, just give rosins a try, you would never know if you would like it until you've actually tried it because everybody has their own taste. Good luck in finding your rosins!
