Irreducibly Complex

This surprisingly hard problem is just to the left of The Prow. It starts in an obvious groove and heads straight up. The top hosts some tiny little crimpers that seem to want to spit you off. It's a great problem to sandbag your friends on. David did this problem quickly and told me it was V4. The next day he showed it to me and we both proceeded to fall on it time and time again. After we both managed to get up the thing, the grade was raised to V6.
