I feel the OP has the right to choose the kind of environment he feels best suit his boys. I've seen people feel both ways about sending their little one(s) off to multi-pet households. I don't believe it's anything personal. Heck, when I was looking for one, I thought I pretty much was going to be getting a 2 yr old spayed female by the end of the week. All arrangements made for the meet-up drive in between (several hours for both sides one way) and then it turns out, just the day before, the owners decide to rehome her to someone closer to them who already had a little male yorkie. They felt it best that their girl gets a playmate. I understand that, and yet, I personally felt it was unfair to me, but I totally understood where they were coming from--didn't stop me from being upset. I even came up with a name for her.
During my search, I've also come upon those rehoming who state that they want their dog to go to a single-pet household only. I've also heard and read about those who feel much the same way as the OP regarding the "many dogs" therefore getting less individual attention. That's even said about breeders with too many dogs.
Of course, with many of you attesting to Mitzis_Mom's character, she must really be a great furmom. But, in the end, what it should come down to is who bfollowell is comfortable with and if he wants to place his boys with someone closer to home or someone who would fly in to pick them up and someone who would have his boys as their only child or maybe as their first set of twins, then that's his right and so be it. I can't see how much more politely he could have turned down a family he doesn't feel comfortable with since everyone's a stranger to him and he hasn't met any of us. Maybe he should just not post a response and just take PM's. It might be more diplomatic that way to just ignore the PM's he doesn't feel suitable while responding to those he thinks has potential.
bfollowell, I have followed your threads and I am as much surprised as I admire how you are not turning this unfortunate decision into a time of profit. What more can anyone ask for short of him keeping his boys afterall and talking his fiancee into accepting them? Doing this now might very well be better than having to do this when the boys have grown more and bonded even more with the new wife and children and then being forced into yet another new situation because the wife really can't bring herself to love them. His loss is going to be someone else's gain, of two very lovable yorkies to call their own for years to come. I do envy the new fur parent of these two guys. I hope they get placed near you that way you might be able to visit with them every so often. It's also too bad that you don't have family or friends to place them with, that way, there's less headache except, of course, they may not already be yorkie lovers like the great YT members here are guaranteed to be.
Good luck on your search for a new home for your boys! I really don't know if there's an honest way to turn down anyone without leaving them feeling insulted and I really do hope you don't feel pressured into placing them immediately with anyone you're not comfortable with. Don't give up on your original intent of placing them with a YT member!
