I compete prelim level eventing (Australian so its a bit different than the US I think) and at a clinic the other day we were jumping around 1.10-1.20 and the instructor said my horse needed a stud girth because he was hitting himself over the bigger jumps.  At the grade we’re doing now he doesn’t hit himself because its not too difficult for him. Do you think it would be a good idea to get one now or just wait until we move up to higher levels? The photo is how he jumps now at our grade. Please judge the photo as well if that’s okay!
