Regarding your general "what kind of person doesn't test a ski binding" Guessing form your epic planks icon you are american, but it's actually very uncommon outside of north america for shops to have ski binding testing equipment, and its only present in america because of your rampant obsession with suing everybody that pisses you off.
Regarding your: "Why not just hit it with a plank?" are you fucking kidding me, even if they are stiff/fused in some way, smashing them open with a plank will probably open them anyway, and achieve nothing except that prove you are a neanderthal that can hit things with other things.
Regarding your "buying marker is insane and a major gamble" that is bullshit for many reasons, but I think your main motivator is the fact that marker just aren't as on trend as they were a few years ago, which is when I bought them, as evidenced by the fact that they were originally set up on a pair of Elizabeths. The fact that pivots have replaces markers as the "cool" binding doesn't change the fact that shit tons of people did and still do use markers, and doesn't make pivots special in any way. In fact it's a very old design.
I also see that you started a thread a few years back to sell not one but two pairs of markers that you had bought and used for a season...... nice try you fucking goober.
