I am a beginner and have been riding a few months. Currently, I take lessons 1-2 times a week and have recently started a partial lease. The owner of the horse I'm leasing lets me use the saddle, which fits the horse quite well, but doesn't fit me well at all.
Should I buy a saddle to fit the lease horse and myself? I'm hesitant to buy anything too expensive, as there is no guarantee it will fit a future horse.
Should I buy a saddle with a changeable gullet that could potentially fit a horse I purchase?
Should I keep riding in the too-small saddle that fits the horse well?
Or is there another option I haven't thought of?
