I'm not sure what you mean by being "boxed in", but I would not suggest inbreeding to someone who was coming at it from that position. Out of all the breeding options, this one should be carefully planned out and thought through.Robert W. Mccoy Jr wrote:
I am in the situation right now where I am boxed in. I have exactly what I want in a male. I have a female pup out of him that is doing a nice job and has impressed the heck out of me.
Your post also suggests that you are very sure about the male, but still seem to have some reservation about the female. It seems, for you, the jury is still out on the female. Maybe, give the female more time until you can see that she is "exactly" what you want as well.
Those who are saying "you have nothing to lose" are gambling with someone elses money. Breeding is not like rolling dice and hoping for the best. Anytime you breed there are health risks to the Sire and the Dam and the litter, there are medical expenses and possible vet bills, shots, food and a bunch of other things that are involved with breeding, so you do have something to lose, including the possibility that further down the road when you've committed to the line from this breeding, something shows up that you didn't know about.
You asked for people who have done this breeding before. From 3 pages of this thread, I've only seen 1 person post that has done it and they didn't give any specifics about the breeding that would help you make a better decision. This should also suggest to you that not alot of people are willing to make such a breeding.
I would not suggest whether you should or should not inbreed, I would simply suggest that you think about it and learn about it as much as you can before you proceed.
