Did the route for the 4th time I think? Always fun and the leaning column pitch is always tough. A lot tougher then the 5.6 (or 5.7 in some other books) rating. Definitely not for the new leader who think that 5.6 is a piece of cake. Not here on the tower. The easiest approach is to hike around the tower East on the trail till you are directly below the Durrance route. There is a set of viewing binoculars there. Go up from there and do the easy 5.5 ish pitch to the base. The other approach is to hike up and around the scree which takes a long time and is probably more dangerous.
