Hi Fred! I am not so sure that western riding is any better for the back than english. One problem that I can see with a bad back is the weight of many western saddles unless you get a synthetic one, which are good saddles by the way. I think any exercies that you can do that will strengthen the lower back would be of benifit. I have a bad back as well, but riding doesn't seem to affect it one way or the other thank God! And my western saddle is heavy! I will say that I have ridden both ways, though not extensively english. But when I did, I sat so straight in the saddle that it did give me a backache. I don't sit as straight in a western rig, but then I don't show either. You have to sit straighter when you show.
As for the scooped seat, that is a cutting rig I would think, designed for you to seat deeper in the saddle if you ride a cutting horse. If you don't sit deeply, you won't sit there long on a good cutter! Different western saddles are made for different reasons. If you are thinking of a western saddle, look for a pleasure saddle unless you are going into something special like cutting or reining.
Happy Trails!
