Quite the diplomat Fluffy!
I think if you have an arid, rough environment horse, that is indeed the sort of thing you'd be aiming for, but IME it depends on environment & other factors as to specifics of a trim, including how much/little of a 'mustang roll'.
I think so too. A trim in a dry climate may be a bit different than for a wet climate.
The purpose of a bevel is to prevent flares and cracks. I think of a bevel as "relieving" some of the torque on the outer hoof, not lifting it completely off the ground-I still think it should be carrying most of the weight-just in an improved way.
I don't disagree with any bevel for the right reason. But the bevel isn't as important as the Reason you are putting it there.
I believe that Pete Ramey gave us guidelines, courage, and instruction, not the Bible on hoof care. I was just speechless when I found his book, and started learning how to use his info. It made a world of difference in my mare. But I didn't stop there. I kept learning, especially from good farriers, and learned to "tweak" Ramey's guidelines to work with my non mustang mare. But he is still the base for my education.
Since my mare had the mustang bred out of her long ago, and lives a different life, there's been some other info that has helped me. Duckett's Dot (mapping the foot like Loosie and Trinity talk about)
