As an owner I'd rather spend a little more money on the bit that would work best for my horse. Not because something is the cheapest, you pay for quality.. And if used correctly, a horse can hold almost any bit comfortably in their mouth. Just because a bit is a curb doesn't mean that it's terrible and harsh..
I've seen people ride their "light mouth" horse in a snaffle and when turning the barrel the rider has pulled the snaffle completely through their horse's mouth. Sorry, but just because you think something is gentle doesn't mean it's always correct.
