So after reading reviews, watching videos, looking at websites, etc, Iāve decided to try the Prestige RP (donut) girth. I appreciate all the discussion in this thread about possible reasons for my guyās behavior! There is a really big question whether the girth is the source of his issues. It could be learned behavior, e.g. due to associations with past bad experiences. Or discomfort in the sternum, pectoral muscles, or even skin. Or something else I havenāt identified. In light of how he acts, I really canāt be confident that heās objecting to the girth itself.
Nonetheless, itās something I can experiment with, and now that I know a little more, I am interested in trying in the donut girth in particular because of the way it lifts the girth strap off the pectoral muscles on either side of the sternum. I want to test whether relieving the pressure a girth usually exerts in that area causes him to object less. This is something Iāve never tried - the Stubben Equisoft does this a little, but not nearly to the same extent. (I am also intrigued by the way the RP allows the girth strap a bit more mobility while the center donut sternum pad maintains stability, but I donāt think that has anything to do with his girthiness).
The other girth with a very similar concept is the WOW FreeSpace. It has a thick, soft, cushy sternum pad on top of which is a completely rigid plate to which the girth straps are attached. The sternum pad keeps the plate away from the sternum, and thus the girth straps donāt touch the pectoral muscles on either side of the sternum. (It also allows the saddle a little mobility, not by allowing the girth straps to slide like the Prestige but via the compressibility of the sternum pad in every direction as the girth straps pull on the plate over the pad.)
I seriously considered this but ultimately decided to try the Prestige, for now at least, mostly because the WOW has to be shipped from the UK so returning would be difficult if I get the wrong size or donāt like it when I see it. Also, the WOW has 2 separate girth straps on each side (like the Stubben Equisoft), and I feel like that just canāt be as comfortable for the horse. If your billets are close together, wonāt there be a risk of pinching? And I just feel like the Prestige RP girth has been around a little longer and is more widely used and user-tested.
I ordered the smaller donut (āPonyā) for my horse who is most definitely not a pony, based on a video I watched. If I understand correctly, this one is better suited for horses with forward girth grooves and less space between girth and elbow. And I took a guess on sizing. Iād normally use a 28-30 on this horse. The video said to add 10cm; other sources said 5-10. I went with 80cm, since 85 is special order. No idea if it will work.
Anyway, I will update when I get it, for any future COTHer who wants more info about this girth!
