Something I did forget to mention, she is pigeon toed (and currently barefoot - though she's getting a new set of shoes on Monday). However, I'm not going to breed her, so if she's not in danger of tripping herself every five seconds, I'm willing to overlook it. Oh, and according to her owner, she's by Zabeel
out of Wild Applause
And I was told the reason she was out of work is because she has warts or sores up her nose that get irritated and cause her to shake her head a lot. It seems she gets quite bad in summer, which is when she had her mini holiday. I'm looking into removal options (or even just a nose net) for this and I'll be getting the vet to look at those before I make a decision.
Matzki; I'm not entirely sure. Probably just amateur stuff as I've never actually competed in show jumping before (I rode my friend's horse in a few showing classes before when she was ordered off, but that's the extent of my competition knowledge XD). This is probably going to sound cheesy, but since my instructor let me ride her jumper over a little 80cm practice course I've wanted to compete.
Kathryn; Her name's Destiny, and she's 15.2h.
Theluckygrey; She's a branded TB - trialled but unraced. She was quite nice, but I suppose I'll learn more when I ride her myself. I had a chat to a couple of students that ride her regularly, and they said she'll put some little pops in if she's excited. It should be interesting, because she's been out of work for three months.
Westonsma; I think I see what you mean. =D Hopefully she'll improve when she's working again.
Thanks for all the comments guys, it's really helping me out.
