DB1 is the softest and most tractive of the three formulas, therefore making it suitable for use - and storage - in generally colder climates. With its very high levels of grip (Grip Profile GPR#8), this rosin can of course be used in any situation that requires greater levels of on-string traction, but care should be taken to ensure that it is not stored above a regulated room temperature of 18 “ 20degree Celsius.
