What are the thoughts on gel half pads? Would people say that they are good at protecting the horses back from the impact of the rider when jumping?

I find if your saddle is newish and fits well they usually have foam panels which help impact more than anything :)
They are mainly used to help the fit of the saddle, but would relieve some pressure from the back. some horses are fine without it.
I have one and love it. I don't jump without it
