That is the perfect size for you. The problem you are having is dry rubber sticking to dry rubber. Just the minor moisture from the slightest bit of snow lubes the system and will allow you much easier access even when the settings are tighter than in your vid. You do not want Large.
Thanks... yea, I typically always believe in sizing down in gear if I'm borderline (I can use Burton small bindings often). Anyways... how do the final settings I have with the Flow look? Is that typically what most people set it too? To be safe, I took out all the forward lean, but I think I'm going to move it back to the "middle setting" now.
