The Kevin comments have me to the point of changing my mind already, however. I was wavering, but leaning toward A1 (and I want to rate it A1). Beyond the thoughts expressed above, the fact that one of the hook placements needs to be made fairly carefully needs to be considered (I looked at it again today while rappelling over it and realized that it isn't as down-and-incut as the others). And, especially, the strenuous nature of the climb. It's slightly less than 40 feet of overhanging aid to the short section where it is vertical. But someone without a fairly smooth aid climbing ability could absolutely burn out and then flail trying to pull themselves up. I think that the best rating is 5.5 A2.
