That is a nice tree. The one in the beginning of the thread was very nice as well. These trees are not cheap by any means, if one can get a good price for material like both of them they should grab it.
I do not have a lot of experience with RMJs. However, usually with junipers, it can be the root work that makes foliage behave this way. Also, I believe, improper or heavy pruning. However, since there was no root work, maybe there is some stress. You mentioned it is pretty pot bound but not due for a repot until 2015. Maybe consider a repot 2014 instead. If something is going on in the root system, waiting 2 more years might not be good. However, the tree looks pretty healthy to me.
It might be that the fungus itself and not the fungicides that is causing the tree stress.
