My understanding is that it should be more of a slide than a step and that's working for me.
So in that case the weight of the gear seems a lot less impactful. Lighter boots and bindings (and even skis) would clearly be a lot easier for the folks I see pass us all the time. With my style it just doesn't seem that I'm lifting all that weight up much.
Thoughts?
Frame or tech bindings, with both the ski should stay on the snow, but your heel should come up. That is the weight you are lifting with a frame binding: the connecting frame and binding heel unit.
There is nothing that makes it impossible to ski big tours with frame bindings. A friend of mine only bought new boots and skis with tech bindings this year, he has been skiing big multi-way tours in the Alps for over 10 years on heavy boots and frame bindings.
Think of it in biking terms: all the famous mountain passes were ridden on bikes weighing twice as much as the current Tour de France race bikes.
That said, lighter gear, and better striding boots, are certainly easier.
I can not really say what the difference feels like, because besides the switch from frame to tech bindings, the skis I mounted them on are much lighter too. So, the fact that it was much easier on my snee set up is only very partly down to tech vs frame binding differences.
