Well i’d like to start by saying thank you again for everyone’s information.
Tim, you are completely right and I don’t know where my brain was when I worded it. Her LS isn’t great IMO, and her loin is long and weak. I’m sure with proper muscling it would be less noticeable, but she’s done nothing but pop out babies for the past 6 years so that’s not really helping her general appearance much. That being said, the title says “short coupling”, which to me is kind of the whole she-bang back there, not just one specific area. I’m more than aware not all stallions can fix this, which is why i’m looking for one that does 
As for Carracci’s throatlatch, I got a whole whack of messages saying "really? that’s what you care about? or “that should be the least of your worries”. It’s far from a deciding factor, more of an observation, really. The mare in question is extremely refined in her throat/head area - she’s been mistaken for an Arabian just going by her head. She consistently throws gorgeous heads on her foals, so this is the least of my concerns. Carracci is at the top of my list, with Beaulieu’s Heartbreaker below.
While I’ve been talking to a few other SO’s extensively via e-mail, Carracci and B’s HB are the two that still stand out to me while others are kind of in the shadows be it them self, the SO or their offspring…
This mare will be the cornerstone of the birth of a new breeding program, so not only do I need the perfect stallion, I need a foal with marketability in my area.
