I ski Japan 30-40 days a year and just bought Atomic Automatic 117s in the 186 length for my one ski quiver. I am planning on doing about 5-6 days of light touring this year (0.5-2.0 hour hikes). I am thinking about putting either Guardian/Tracker 13 or Marker Baron bindings on the Automatics and using my downhill boots (K2 Spyne) to hike. I am not looking to spend money on an AT/tech setup since I will primarily be skiing lift accessed powder.
Last year I used the same boots with snowshoes for 1-2 hour hikes, and with the buckles loosened my feet/ankles had no problems.
Is the Automatic + frame binding + downhill boot setup too heavy? My legs are in fairly good shape and I run quite a bit when not on the slopes. I am 5'11 160lb. Appreciate any input. Thanks.
