Of your 3 entries I like the symbol in #4 best, though only because the symbols in the other 2 look too "hard" in colour and shape. I think the orange softens it up as well. I also wonder how the name would look in your designs if only the first letters were capitalized. Looking forward to seeing more designs.
By the way, I think I like the symbol in #4 because it says something slightly relevant, someone taking a leap. Perhaps they are landing. Perhaps we could give them a ledge to land on (but maybe that would be too cheesy).
I'm not committed to the leap metaphor, but this kind of suggestive action in a symbol might work.
#9 is good (don't withdraw it), but I wonder how it would look if you deleted the line to the left of the person's right foot (eg. so it looks like they landed on a ledge).
