That last picture shows a more true image to your mare than the originals :) Personally, I love her. Yes her neck is a little short, and I agree that her back is a tad short as well, but you say her movement is to die for and thus far nothing has held her back. I think your breeding plan is reasonable and the marketability of the foal as a registered baby will be more than respectable - as many others have said, I'd go with stally #2. I like him better overall to add the refinement and height you're wanting to your mare. I like that you're not gung ho to breed either, if it takes you a year or two to find the perfect stally and right timing, so be it! Your mare not being maiden helps as well! Good luck and let us know who you go with and when!
