Motrya Gold is the best! I wish,I had discovered it sooner, I wouldn’t have kept searching for the perfect rosin tone. I’ve tried many- too many brands, Korean Tartini/Andrea Bang and many European brands but I truly did find gold with Motrya, nothing else compares, and much less expensive than Tartini. It’s so smooth, produces a lot less dust compared to others, the tone is powerful and clear, amazing projection.
