To be honest, I hadn't even heard of LMF feed until I googled it just now form your post.
Looks to be a bit better than Strategy. Just an FYI, this was a bad year for lamimitis around Kansas with the wetter than normal pastures greening up the cool season grass, and I had more emergency laminitis calls from Strategy fed horses than any other. It's too concentrated, so it's super tempting and easy to overfeed. I don't think it was the feed itself, necessarily, but that, with the sugar situation in the brome fields, it created too many straws on the camel's back, so to speak and something had to give, unfortunately, it was the horses's feet that gave. So I'm glad you are looking to switch feeds.
I would suggest a feed that has NO molasses in it, though. the Gentle formula of the LMF has some in it, and it really has no place in a horse feed. I'd rather see someone add a cup of oats before an ounce of molasses to make up calories, and horses don't mind bland flavors if they aren't used to sugary feeds in the first place.
