I thought 'Going' was about the same difficulty as this route if not a little harder, but the length of 'Dunka dunk' makes it difficult and scary(in high winds at least).

This seems to be going against consensus, but I liked Dunka better than Dunka Dunk. Dunka Dunk has one less loose foothold after today, though.... There is some loose rock to watch for when topping out and when pulling the rope, so make sure your belayer isn't napping. (Probably good advice in general.) Both routes are fun!
Scott, I also think "Dunka" is a better climb mostly because it has better rock. "Dunka Dunk" has a bit more climbing and is a bit more sustained, but it has more choss!
