Combined with the changeable gullet you Cair makes a very versatile saddle.
I disagree. The Changeable Gullet makes the saddle fit the withers, not the shoulders or the back. Then there, lays faults in itself. You adjust the Gullet to widen, you now cause the issue of bridging. You can accomodate the wither, but you cannot accomodtae the back and you can accomodate the back, but you cannot accomodate the wither.
You have to ensure that the panels and the saddle shape fits your horses back accordingly - you do not fit a saddle only through the width of the saddle. Whether it be Medium, narrow, wide, medium wide - there are far more to saddle fit than this - and that is where Wintec/Bates fail.
That is when, and only when a professional fitter/maker can help you. Then and only then, can they help if the saddle is wool flocked, and made with a hermes sprenger tree, or an adjustable tree - not a wintec or your commonly made leather saddles.
With a Cair you can generally alter it to fit yourself.
I am curious to know how one can adjust the C.A.I.R panels themselves?
I know that with the older wintecs you could flock behind the cair panels if you needed to change something
The Older Wintecs did not have the C.A.I.R panels
