I'm trying to better understand the order of my stacking and I'm a little confused and finding it hard to choose between SX or SP. Given that I'm an E6, it's hard to decide which one I prefer because at the core of six, aren't they all looking for security like an SP? That makes me think SP would be first but then the SX descriptions sound a lot more like myself ....but the whole basis of the E6 is a need for security so how do you choose accurately? I'm confused. If anyone has any insights into what they think I might be, it'd help. The stackings are so straight and to the point but I'm having a hard time seperating which one is more important as they both seem equally important to me.
