I've spent a month now learning to trim my horses. I had a farrier out to help me with their frogs and to make sure I'm on the right track. He said I've done a good job and the balance was only barely off in one foot.
I'd love to have a critique from another set of eyes!
It's very hard to say anything about balance, but they look good overall. Frankly you guys should be very talented if you can do balance correctly. I trimmed my horses for while and took a month of trimming lessons at the university (with the professional farrier who's in business for 10+ years), and I'm still not very good about balancing them properly.
I would personally give the toes a harsher roll. And that will prevent them from chipping like they have been. I would also take a little bit more of the bars out and switch them to 6 week trims. 4 weeks is just to close together and more labor for you. You also want your horse more on its soles as just picture you walking on your finger nails or toe nails is like them walking on thier hoof walls.
I used to trim my own when my health allowed it. Good job I think it makes you a better trainer when you learn how hard your trimmer/farrier has to work.
I think they look pretty good so far; I second to take a bit more off the toe itself, and a bit off those flares.
I actually prefer a 4 week schedule, because even though you are doing a bit more work, you have less to file off, and you can correct problems easier, because they have less of a chance to 'get' that way, if you are on top of them.
