Can i jump in a VSD saddle?
It looks like a standard GP saddle to me, there doesn’t seem to be a straighter front panel. If the one you have seen has knee rolls, but a straighter front panel, it could be a working hunter type saddle, which was what I used to own. Basically it was ideal for showing in WH classes, as the shoulder action was more visible for judges (like a showing saddle), but the knee rolls still offered security when jumping in this part of the class. I did everything in mine and it was spot on. It was actually better suited to my mare as she had quite a large shoulder on her for her breed, so was more comfortable for her and a better fit overall.
