I like the logo a lot actually.
Pros: The simplicity! (so many people try so hard to make the coolest logo that is going to stand out, but what they dont know is you dont need something so extravagant to draw attention.
The fact that when i look at the logo I get the idea that whatever the logo stands for will bring an adrenaline rush and something physical. Thats exactly what you get from rock climbing.
Cons: Like they said ^ the font is very willy wonka-esque
So all in all i think the logo delivers everything a company would ask for. Sure i have worked at a graphic design place, but im no expert at all. My best advice would be to write down everything that NS says and then take it to somebody that knows truly what they are talking about and then tweak your logo based on all of those facts.
