^^ Couldn't agree more. I've seen some wound tight horses in eventing, but they're always held back because they just can't pull off the dressage without some sort of fireworks. Personally, I just wouldn't want to deal with that (and I usually like a challenge) especially on XC. You don't need a horse who is scitterring all over the place, poor people walking the course. Lol.
My horse was listed as a trail horse, he is so used to everything like 4wheelers, dogs, scary looking stuff, that none of the goings on or cars on course bother him. An event is just a big ole fast trailride for him.
The second horse sounds much more appropriate. Don't be afraid to look out of the discipline... a horse with a solid flat foundation will certainly get you through the beginning stages of eventing. What you really want is a quiet sound horse.
If your horse says no, you either asked the wrong question or asked the question wrong
And God took a handful of southerly wind, blew His breath over it and created the horse
