LOVE them, like actually love them. My saddle doesn't fit perfectly (surprise surprise) so I did my best to find the closest fitting saddle in my price range, but of course, there were still going to be some glitches.
So I found ThinLine. I got the western ThinLine saddle pad, and it changed everything! She stopped pinning her ears when I saddle her up, started moving more loosely, just happier. It compensated for the little glitches from the saddle.
Two thumbs up!
