I have a Sir James yearling and she is very correct and a phenomenal mover. She has a natural step to her canter and is very elastic. I still have to stop and watch her when she plays in her paddock… I see a lot of her dam in her so it didn’t just come from her sire. I could easily see her doing hunters, she has the step/movement for it. I also think she is going to be huge. Her dam is well over 17h and Sir James is very large himself. I think she’s going to top out at 17.3+…
I am curious to see if there are other Sir James horses out there competing. I haven’t seen anything recent from SJ himself.
So I am clear, OP - you want the 17h+ range you have now? What does your mare need improvement on? Only movement? I imagine with that pedigree she may be a bit old fashioned depending on which C-line stallion you have? I love Galoubet A but he did not always make a pretty mover, he made a fantastic jumper though…
Personally I am a huge sucker for Landkoenig horses. I think they are beautiful but I am not sure if he would pair well with your mare’s pedigree. I also really like Navarone but some people think he passes on difficult temperaments. I have not had that be the case, IMHO, but every horse has a dam…
Out of your list I think Redwine despite his unfortunate history, is very amateur friendly…
Westporte has some very nice moving horses, very beautiful to my eye too but I don’t have any experience with whether or not they are amateur friendly.
Gatsby would give you nice movement but if your mare is big and has a lot of bone I am not sure I would breed to him. I would definitely breed a refined mare to him. I see him consistently add height and bone. Great temperaments.
Depending on your mare’s pedigree it might be a challenge to find a hunter sire that doesn’t have the same relatives - you can’t throw a stone without hitting a C-line or Galoubet A horse sometimes… Cunningham was my first suggestion until I saw you say your mare’s sire line.
I like Crown Affair and Quite Easy, personally. But not sure if they are appropriate given your mare’s pedigree.
