I do not sell saddles and therefore have no vested interest in telling you that your saddle doesn't fit.
However, I am very familiar with the struggle to find a well fitting and affordable saddle, and have used EFT on myself to clear the guilt and sorrow I felt when I first discovered what pain I had been putting my horse through due to his professionally fitted saddle.
I now have a great deal of experience with saddles, due to my own struggles to find the right ones for my own horses.
One of the most useful tools I have found is a Port-Lewis pad. I can put this pad between your horse and his saddle and, on removal, it will give a clear readout of the pressure pattern it creates on your horses back. This can clearly show how you, your horses and the saddle interact.
If there appears to be a problem, I can put you in touch with a Balance Saddle Fitter, who is qualified to help you find the right saddle.
