For several years I have been playing with a personally customised rosin recipe from Leatherwood Bespoke Rosin on my bows.
This rosin absolutely overwhelmed me: the responsiveness of the contact point, which goes hand in hand with an enormous intensity and sound density, the carrying capacity of the sound and above all the design options are really on a unique level. The fact that problematic contact point zones are easier to control makes it easier for me to implement many colors and ideas on my instrument. A nice bonus is that the rosin hardly produces any dust and it really lasts a long time.
I have recommended Leatherwood to many friends and colleagues who are now enthusiastically using Leatherwood as it minimizes many problems and creates new opportunities for them too. I urge everyone to try the different Leatherwood recipes, because with them you can find a partner for your musical life. I found mine in the 65% Crisp / 35% Supple.
