Since I have no personal experience on this one, I'll just keep my mouth shut (I also just received D.R., and am going to begin reading it tonight, so maybe I'll have more professional knowledge bestowed upon me later). However, I agree with the wait a month and reassess tactic and GALing in the meantime -- the reasoning for this sounds sound.
Hope everything goes as well as possible for you -- it does sound like all else is very positive!
And, for the record -- I don't know diddly about fish!
