I must say, Kannan with the right mare is interesting. Hunter is a good suggestion, but, I’d probably like him on a mare I could count on for a few things…his movement & that of some of the offspring easily found, are kind of typical with Alcatraz who can have various types of steps, his seems a bit up & down, but I’d say the mare might have more say in this than Hunter? Unknowns given he hasn’t been used that much, and why I might use him on a more proven mare.
Worth a look is the young stallion Ehrentanz.
Depending on your mares type, there is also a SF stallion Krisproll One worth looking into. Flexible is obviously worth a look, too.
I had the pleasure of seeing Quintender gallop & jump…he has a fantastic gallop, he looks like a TB. However, enough real blood for an UL horse? I’m not sure…
Has Ciceras Icewater thrown a real UL eventer yet? I think he’d suit modern eventing well, but it may take an F2 with him.
Your mares type is probably the biggest question. There are some more, but, I really can’t suggest them without a type.
