I have a Polish bred mare! I love Polish Arabs, they're my fave.
I know in my girl's case, her bloodlines are almost entirely made up of racing-bred Polish Arabs. And she is, even at 28, a fast little cookie when she wants to be!
I've had fun races with friends a few times and Lacey has never lost.
Typically, Polish-bred Arabians seem to be the ones that are the most versatile.
I know my girl spent time as a youngster being some kind of dressage horse, then she moved on to a extreme trail pony, then retired for 12 years, then came back (after I bought her) to be a less extreme trail-endurance pony and lesson horse. She also LOVES to "herd" things. Show her a cow, a llama, whatever, she doesn't care. As long as it moves when she pushes it, she's pushing it.
She also (before I knew she was mostly blind!) did her best at jumping. But she was a pretty terrible jumper (probably the whole blind thing), though she never actually botched a jump other than choosing a weird spot for take-off, so that's not something we do.
And, of course, while she's doing all that^, she has ERU (moonblindness) and is close to 95% blind.
Talk about versatile with a heart of gold!!
ETA- can't tell you all that without a picture!! What AM I thinking! hahaha
She's a stocky model too - it's a pretty typical trait among Polish Arabians. I love it!
