Witch stallion to use for a big heavier mare?

[Michaeljames101]

Hello everyone, any thought on a sire to use ? I have a mare that is heavy horse x so not completely heavy but not fine , I would like to to add some blood and hopefully get a more refined and pretty offspring , something with a longer neck and better back end as she lack in those department however her temperament is and an absalutely dream, mainly wanting to show jump she has jumped up to a 1meter

We're probably going to need more info to make sensible suggestions. How is the mare bred? What height is she? Do you have a conformation photo? What are your ambitions for the foal?

Chrysler Key might suit, but without the above it's a bit of a random guess!
