The reason I ask is because Fritz was extremely bratty the last time I rode him on my first trail ride. When we got back to the barn, the instructor (not my normal instructor) told me that if she were to ever buy, or even run the barn, the first thing she would do is put a more aggressive bit in Fritz's mouth.
It's kind of confusing because I get conflicting information from the two trainers out at the barn. I can see two different teaching techniques between the two. My usual instructor is very laid back, super nice, and doesn't push hard at all. The other is more about getting results, she's firm, yet supportive. I really like the both of them, but honestly I feel like I learn more from the other, vs. my normal.. Anyway, that's a bit off topic.
So anyway, I was just wondering, if you were to introduce a new bit to a horse, is it just slap (not literally) it in the horses mouth and go, or is there some finesse involved?
