The cutting works for some horses and doesn't for others. Much like it works for some riders and not for others.
I don't want a horse that gets hot easy personally. I like one that has lots of get up and go, but not hot. I don't like when I do a manuver and my horse is like shaking with excitment, a little amped up is fine but not a lot. I don't want something that is so ready to make a move that if I even move my hand half an inch they are bouncing all over the place. I like a quick but smooth reaction.
Soft and responsive is very much what I want, but I don't like a horse that is moving just as I'm starting to think about asking. But for some people that works, just like many people don't like my style of horse.
There's tons of horses I think are REALLY nice horses, but I will sit there and tell you I don't ever want to own them. I know what kind of horse I can and cannot show well, and which ones I'd get along with its that vibe you get ahha!
