I just got back in from trimming hooves and was curious which way you all use to make sure you have a nice even hoof. I like using the growth rings as my guide, but I know there are other ways people go by. I'm going to have to go back out in the next few weekends and finish them up, I was getting to the pink and not quite finished. Also do any of you use a rasp/file? I bought one from hoeggers and it is somewhat akward, and I'm not sure if I like it's results.
