Why do you prefer Jade rosin, just curious? I have never used it before, but I have read that it is more ‘sticky’ than the lighter rosins. If it works for you and you are happy with it, I am not aware of any problems in using it. Personally, I use Leibenzeller rosin, but it’s pretty pricey. I bought two versions of this rosin 30 years ago. I am still using the one I like most. It’s about 1/2 way down. A great deal depends on your bow and violin combination. What the sound potential is from your violin. How well the bow compliments that with your own playing. The strings you’re using. And then, your preference with the rosin. A violinist spends a lifetime tweaking all these things, so be open to trying new products and methods if you just aren’t getting the results you want.
