Well...what I consider an "off breed" FOR ME is a WB. Some lovely horses but mostly BIG. I am not a fan of big horses. Physically, they intimidate me just with the mass and height. I have owned one WB (Oldenburg) that was not big. She topped out at a massive 15.2...but, she was the most challenging conformationally and dressage was just too hard of work for both of us. She never grew up but got long and ended up downhill (I bought her as a relatively normal compact looking horse. I affectionately call her my little dachshund...of course not her fault. She was of more jumping bloodlines. I sold her on as a all-rounder as she could jump and was good on the trail. I picked up a catch ride on a 16.1 Oldenburg mare for a few weeks one summer. I would call her a nice but fairly average mover. Honest to pete, after a lot of work, I got to where I could sit her trot for about 5 strides. OMG, I don't want to work that hard.
SO, I am more interested in a certain height than what breed. I want a horse to be 15.2-16 hands. Wouldn't turn down shorter (down to 15 hands) if it was broad enough to take up my leg. I am 5'5" but right now a bit doughy after nearly a year of staying home and eating

I started out with Arabs and part Arabs. I had a lovely little purebred gelding...not the most arab looking (Polish bloodlines) but mahogany bay with lots of chrome that was a really nice mover. Unfortunately, he got early onset hock arthritis (@7-8yrs of age) and was born before the advent of joint injections, joint potions and the like. I did successfully re-home him with a friend and he became a mountain pony of excellence after his hocks fused.
I have had one Arab/Hanoverian mare. Bought young and she turned out just a little bit 'weedy'. Not really a lot of traits of either parent? She wasn't ugly by any means but she was a bit short pasterned and sitting trot was a challenge that did not thrill my stiff back. My instructor at the same time rode her a bit and concurred. I got her to 2nd level then sold her when I fell in love with above WB filly at the farm I was boarding at(down side of boarding at a breeding farm).
Certainly, Kyra has been the best suited to Dressage for me. She is 15.2 and an Andalusian/appendix QH cross. Oh, if only my body hadn't given out on me the last few years. I was just on the precipice of diving into 2nd level when I started having some pretty major surgeries...one after the other

. I hope that is over now and can get back in the swing of things this year. I did ride more last year than the preceding 6 years put together but I still need a lot of fitness work (and so does the horse).
I have always had a soft spot for Arabs and Arab crosses. I like more go. I don't want to have to pedal constantly. I wouldn't turn down another Andalusian/PRE or Lusitano but like most of us, I don't have the budget for that. There are some nice crosses out there. In another post, I posted a farm that is breeding Lusitano/QH crosses that look very handy. Kyra looks very Iberian and was a whopping $3,900 (as a coming 2 yo). Thank you small breeder that was horse poor.
I am sure at this point, as far as moving up the levels in Dressage, that my boat has sailed. That is OK. I still love dressage for the training and what proper mechanics can do for the horse. Just look at the before and after photos of Straightforward's Annabelle. Kyra is probably my last horse. If she makes it to old age, I will be in my mid-70's. I may look for a dead calm lease but we will see. It sure is fun to shop for other people though
