Looking for an uphill KWPN stallion that can give blood to the mare. Mare is a sweetheart - greatest conformation too just needs more energy.
Of the Heartbreaker sons, I love Quasimodo vd Molendreef. But might also consider a stallion like Corland. Those I have seen tend to be quite bloody and great partners in sport.
Im a fan of Orlando, By Heartbreaker out of a Darco mare, a lovely type and super jump, I have a KWPN mare in foal to him this coming season http://www.sporthorse-data.com/d?i=362962. I also like Quasimodo vd Molendreef and Upgrade.
V. Shake baby? Congrats on buying such a lovely horse. 
You would do well to speak to her breeders, they are very knowledgeable and would be able to help you choose a stallion for her that matches her breeding.
