This is, once again, a lengthy question. For 2015, my New Years resolution is to learn how to slide. I know, I know, for a dh rider I have everything else BUT the necessity of knowing how to slide! (Bring on the hate) these are my two boards. My madrid doesn't have much concave, but it's enough to keep me on the board...If that makes any sense. Plus there isn't any possible way for wheelbite, sooo yeah. But my other board, makes my feet feel more locked in. I took some pictures of my stance on both of them, (I'm goofy) as well as a shot of my mini zombie hawgs so you have an idea on what my setup would be. On my pintail I have caliber 2's, and on my madrid I have Paris v2's. I gave both of my boards' trucks a good flex today. They are relatively the same as for performance, so I don't think it would be much of a factor. (Or would it?) If you would have to pick one, which one would you choose? I'm leaning towards my Madrid, I'm just hoping that I wouldn't fly off. But I suppose I won't know until I try, right? Kind of off topic; I know squeaking is normal when you're not moving your board but you're standing on it and leaning back and forth, but my Madrid today was making this awful loud creaking sound. Like stepping on an old wooden floor. It's never been this loud before. I'll see if I can upload a video sometime so you guys can all hear it for yourself. I think it's just because my board is older, unless it could be something else. If you read all of this, I really appreciate it. I would've googled this but I don't think it would've been as efficient, since Google can't see my boards and all.
