The metal-reinforced Aftershock in the A.M.P. family (All Mountain Performance) combines two sheets of titanal above and below the wood core, designed to give advanced skiers precision and power. "Too carve-oriented to be called playful," said Crawford. "It's stable underfoot and digs into medium-to-long radius turns." Stability underfoot comes from K2's Hybritech Sidewalls, which blend sidewalls underfoot with a lightweight cap construction in the rockered tip and tail. Mod Technology's secondary core flexes and absorbs shock. "This ski dampens vibration well and instills confidence at speed," said Mahon.
