Okay, I am going to try to translate this:
We have had to buy three saddles for my horse. It's getting expensive. The first saddle I bought with my own money. The people said it fits him great. They lied. We had to switch him to an Australian saddle. He did really well with it, so we had to switch to a saddle with full quarter bars. We got a new saddle that fits him but it makes his back hurt. Don't say, "well, it's because it doesn't fit him." I'm tired of hearing that. I may have to switch him to English or just get a new saddle pad. He's not my first horse. Just making that clear.
So, if I got that right:
1. An Aussie saddle fit but instead of using that saddle another saddle was purchased. Why not keep the Aussie if it fit?
2. The new saddle supposedly fits, but hurts him. Well, OP, if it hurts him, then it doesn't fit. Even if you don't want to hear that. Or, as someone else posted, the horse has back pain/stress/injury that needs to be resolved before any saddle is fitted for him.
Are you asking if you should try an English saddle on him or just try a new saddle pad? The answer from me is no to both. If you ride Western, then you need a Western or Aussie saddle. If the saddle doesn't fit, a saddle pad won't fix that. It needs to basically fit. Some adjustment can be done with pads and risers, but if the saddle doesn't fit, it just doesn't fit.
Perhaps if you posted a picture of the horse with just the saddle on his back (without a pad or blanket), someone will be able to tell you how well or poorly the saddle fits.
