I like your type treatment. And the color choices are bold and compelling. But two considerations: 1) we're pretty determined to build the visual elements into the type itself, and 2) even if we did choose a side icon, as in #24, I'm not sure that's the right visual. I think it's kind of cool in its own right, but it doesn't make me think of "analytics." That said, I like the button approach ... almost like an "easy" button (if you know the American commercial for Staples). Perhaps, given our emphasis on simple analytics, we could play subtly off the idea of an "easy" button (http://www.youtube.com/watch?v=2yK_PELRHTk). It could be an "easy" button for web analytics.
Can you try #24 vertical stacked? So "spring" above "metrics", and you would probably need to swap the treatment on them (bold color on top). Not sure where the icon would go for that. You may want the "metrics" to be the same size as spring, or perhaps much smaller.
