You have had issues with just about every trendy French saddle company (you started threads on not only Voltaire but Dev, CWD, etc.)
For once why not go with an independent saddle fitter that can sell you a British saddle designed to be flocked with wool that will actually fit your horse? I know, it’s NOT TRENDY. But how many times do you have to get burned before you decide to do something different. If trendiness really matters, then how about trying a County? I still think a FITTER who KNOWS WHAT THEY ARE DOING and does NOT WORK FOR JUST ONE COMPANY is better-- but at least the County saddles come in wool and have a variety of shapes and fitting options. And while their reps work on commission, they tend to be a bit less “hit or miss” than the trendy French brands.
I do not have a lot of confidence that a saddle that was designed for foam panels (thinner than wool and shaped differently) that has been remade 2x and doesn’t fit can be fixed by Voltaire to now be a wool saddle that will fit. i actually have almost no confidence in that. And I am not sure many good saddle makers are going to want to or be able to try to convert this to wool-- or that it would be cost effective. If I was going to convert it, I would pay a true saddle fitter to do it. I would not try to get Voltaire to do it. A saddle fitter worth their salt will know if it can be done and done right. Might not be worth the cost though.
You could sell the saddle used, buy an Albion/Black Country/Ideal/Hastilow, etc., have a saddle that fits, and have money left over.
The French saddles are PRETTY and it’s nice when they fit. But yours doesn’t and you’ve been around and around with the French saddle reps. Their job is to MAKE SALES. They are not necessarily experts in saddle fit. I suspect they’re going to blow whatever smoke it takes to get more money out of you and then you’ll have a f-ed up Voltaire that you CAN’T easily resell and it still doesn’t fit.
Sorry if I sound frustrated. I am frustrated FOR you… but at some point you have to stop doing the same thing and expecting a different result. I don’t think retrofitting a Voltaire to wool is wise. If they couldn’t make the foam fit, and allegedly foam is their jam, what gives you any confidence they can make wool fit?
