I was pretty picky about our donors (had three). I considered EVERYTHING. After we had failures with all of them we were offered donated embryos.
The donors of the embryos physical characteristics and their histories were nothing like ours. We never would have chosen them (felt zero connection). But we were tired of the failures and just wanted our baby. We accepted the embryos and have two beautiful children. Crazy enough, they look like our genetic kids although it really no longer matters to us.
I guess I am just saying circumstances may change your priorities.
Best of luck to you!
Also, I would go with a young proven donor. The donors we failed with were not proven and that was a big regret of mine.
