Guru Blue truely shines in fresh to transforming snow in the -4°C to -10°C. It sure is a joy when the weather lets you have the snow conditions this wax. You will find yourself reaching for this wax, more often than other blues in your wax box. Still hard enough to use as a cover/mix for speeding up some stickier waxes. If it is a bit more mild, or the conditions are changing, use the Blue Special instead.
