Only you know what you can live with - inconvenient, but true. So, the question is, are you always going to be anxious about what's going on in the remaining breast or are you going to be able to put it to the back of your mind? I wouldn't worry too much about the recon as that can be done at the time or later if you want it (although obviously another surgery) so maybe keep that thought process separate. Whatever your decision is, it has to sit right with you so that you are satisfied that you have done the right thing, now and 10 years down the track.
