The Ski*Go XC Klister Series is quite large for a klister series so to be able to pick the best one from the bunch on a given day requires some powers in divination given how quickly klistery snow conditions evolve over the course of a day. But since klister rarely fails to give you bomb-proof grip, predicting snow transformation is usually inconsequential especially if you have the XC universal or XC silver klisters. Or if you come up with a clever mix of two of these klisters. This series of klisters is fun to play around with for sure.
