Does anyone have any advice about adjustable tree saddles? I don't have a horse currently and I ride a number of different horse body types, so an adjustable tree (or gullet kit, or whatever the brand offers) sounds ideal to me. I always ignored the adjustable trees because they usually come in Wintecs or other synthetics and I HATE synthetic saddles and I'm not a fan of leather Bates either. But now reputable leather saddle companies look like they're coming out with adjustable trees or gullet kits so I'm wondering if I need to re-think this. I haven't found much info on them from a horse-health standpoint. Obviously the saddles are popular so that speaks for itself, but I've also heard that adjusting the gullet does nothing for horses that need different tree sizes and that adjustable gullets can really harm your horse. Any suggestions? If adjustable gullets DO harm your horse because it doesn't solve the problem, why do saddles offer measurements for trees based on the gullet? That's where it hits the shoulder. So why wouldn't an adjustable tree work then? Just wondering. I'd love some advice from someone more knowledgable.
