Well, I answered my own question. 930 release and the classic slalom toe bar, plus the Vapor plate.
When setting the tension following the instructions for @Horton’s video, I’m lower than reflex’s recommended setting. About a 3.5 instead of 5. I think it’s the “hybrid” nature of this boot that causes this. When I started at the recommended 5, the binding didn’t release at all and it felt like the liner portion was “releasing” like it does when attached straight to the ski.
anybody else find this to be true? I’m pretty sure I didn’t mess anything up, just curious.
