It's quite the argument, but you are pretty much correct, Line was making the skiboard movement and hadn't moved to full length twins just yet, and Salomon had been developing the ski for the riders, but was not the first to get to release it to the public, only the team riders rode it before the Poacher came out(Make note, thats like right now, everyone skiing on non-twintips and seeing Thall ride armadas, EVERYONE knows about them and wants them.)
Either way, everyone dropped their first twins around the same time, and not one company single handly changed the ski landscape.
