#1 item: Leatherman: for any tool that is a must have, Leatherman can be made to work in most situations (I telemark)

Im radical about having a simple headlamp. Been involved in many rescues over my career where people who got in trouble simply ran out of daylight only to compound the problem.

Duct tape: not a roll, but a generous wrap around the ski poles. Can be used for a blown out pant leg, first aid or whatever.

Seems a little "limited" to me! Especially the "communication device", cell phones are notoriously unreliable in the backcountry! A binding that blows out might need more then just screws in some cases, as you might not be able to just screw a new screw into the old hole! I would include some epoxy and bailing wire. Also include  various sizes of hose clamps in case one breaks a pole (can also be used to fix both tele and AT bindings)!
