Salomon’s new Pocket Rocket ($775) has big shoes to fill: It replaces both the company’s Super Mountain and AK Rocket, two very popular skis. How does one ski make two obsolete? Extraordinary versatility. A fat ski with twin tips, the Pocket Rocket is a response to new school tricks moving from terrain parks and halfpipes to powder-choked cliff bands. But with quite a bit of sidecut and a crisp, light-weight feel on snow, it can romp on the groomed as well.
