I'm very uneducated when it comes to bits. I know the basics of least harsh to very harsh, but I want to know why. Here's my understanding as of now. The least harsh bit is a french link, then a snaffle. Typically snaffle seems to be the "go to" bit due to it's simplicity.
I remember reading one one forum that a slow twist snaffle is harsher than a regular snaffle. The tighter the twist and thinner the bit--the harsher. Why is that?
What makes this
Harsher than this
It makes sense to me that adding shanks will increase pressure, due to the laws of physics. I get that having a smaller piece of metal can cause a more precise point of pressure, which could make it harsher, but if a snaffle and a slow twist snaffle are of the exact same thickness, why is the twist considered more harsh?
Just interested in learning more about a subject I know very little about. Thanks!
