For those who like to shout: When all 4 wheels are "all-weather" on ice - before skiing it slides forward, and the back continues to push confidently. I specially put spikes in the front of Kama Flame, behind - I left the "all-weather" Kama Flame and went to the ice track. Appeared handling before rakes as it should! Well, a breakdown in an uncontrolled skid occurs almost simultaneously.
