RTF Saddles?

Does anyone have experience with the Rotate-To-Fit (RTF) saddles? Dover’s Circuit Elite, M. Toulouse, and HDR all make saddles that can change gullet width with an allen wrench or hexagonal key. Would love to hear people’s thoughts or experiences with them

Just got one this week for the SO. Adjusted saddle to fit as the width it came set to was pushing down on the back of the withers. He sat in the saddle today and liked it, will try it again tomorrow to be certain.

We took the chance on it as it was a closeout and the lifetime tree warranty.

I tried the HDR Rivella version once. I discovered that the RTF mechanism takes up quite a lot of vertical space. So a saddle that otherwise would have cleared my TBs’ withers did not. Take-home for me was that these saddles won’t work for a horse with tall withers.
