I used to be an avid Cecilia rosin user. This one is much better. It has more grip and it projects well. I've been using it for solos. It works well with all strings. It has a smooth tone and doesn't give a scratchy sound. This rosin does last a while, I am an intensive playert and find I only need to rosin my bow once a week. You also don't need much after the first initial rosin, just 4 swipes will have you good to go.
