I use Jade Solo rosin when Im doing concerti as a soloist. In my experience it is great for fast bowing response and articulation. Sometimes it grips the string too tightly and prevents the string from starting (happened to me once while I was performing the Bottessini concerto

lol) but with a little practise you soon get a feel for it and it wont happen. Just make sure you dont over apply it as its grip is incredible!
