In most ways my horse is my perfect horse. He's great on the flat, likes jumping but doesn't like it so much that I think I'm wasting him by not doing loads of it, loves hunting, is nice to handle, generally a nice sort to have around and very sweet. The only thing I would change is that I'd love him to be a hand smaller. I'm 5ft4 and at nearly 17.1hh, he's a big chap and really too big for me. Thankfully he's only ever been ridden by small women so he's easy enough to deal with, but if I had to pick at something, it would be height.
Next time around I'll be looking for another IDxTB but a hand smaller if poss!
Am on the third perfect one. Middle one's occasional bucking may not have been totally perfect but I still have him after 17 years so he must have been doing something right.
I'm really heartened to hear that there can be more than one perfect horse in a lifetime. My old PBA gal has been perfect for me - light enough to ride classically, sparky enough to be fun, and sensible enough to hack through a field of stampeding heifers in a force nine gale (albeit it in very bouncy shoulder-in). But her sarcoids have worsened considerably this last year and it's really hard to be optimistic about the future...
