Like every fitting, it depends on the actual fitter. I bought two used saddles from Schleese and a third new one (jumping). All was well until I bought my new horse. I had the saddle tried on him to see if it would fit, it didn't and destroyed his back. Has taken me six months to fix it. So I am miffed, and though I have Schleese saddles I use a different fitter.
Never take what a fitter says for granted!! Ask questions and use your own judgement as well.
The fitting is pretty simple. They look at it on horses back, take measurements, have you ride in the saddle and see how it fits. They are nice saddles, I like the three I have!! I just was unhappy with fit. Also, they are in Canada so any kind of repairs etc take forever!
