I love the look as well. Plus, its a good way to keep everything labeled and in ownership. No more "borrowing", if your around a lot of other people.
I have plates on both my jumping saddles, all my leather halters, and I have the round tags on my bridles, but I've been wanting to get a real plate that screws in as of late. I just have this thing about having holes in my bridle.... But I really do love the look. My trainer uses them on her martingales and show girths as well.
