Karakoram Dual-Speed Riser

This thingy works alright… on the floor in my living room. In the real action outside I faced a bit different reality:
The risers are quite tricky to lift with the pole basket, so bending down is the quickest solution.
The heel lock simply doesn’t work in icy/snowy conditions as with the accumulation underneath the heel you can never achieve the perfect alignment with the pins and they just push the heel lock bracket downwards without engaging. Frustrating…
