IMHO, roos are very hard to place and unless you are willing to take them back - no matter what - then you can't dictate too much about their future. A roo can get picked off at any time as can any chicken dogs or no dogs. If I were you it seems like you have a decent placement that is willing to live by your terms so I would place him.
If you don't place them with her you will have to figure out a long term solution because you may never know when the next home may come along. In my experience around 20 weeks old the roos really start chasing the hens and will have to be separated for their safety if you have too many roos.
Also, what is your plan if the rooster turns aggressive to her. Are you planning on taking it back?
