Wow! So glad you made it! Too bad it was not such a great experience.
Most people climb the left side of the main gully up to the notch, but I am not sure it is that much different. There is a lot of bouldering and some loose rock to climb there as well.
It is interesting that, although you are a rock climber, you were pretty intimidated. Maybe the fact that you weren't connected to a rope made you feel so uncomfortable.
How does your route compare with the videos in
