If it makes you feel better, I’ve only done starter at recognized events (including JS which was my first event on my current horse). At the time there wasn’t much difference in price between schooling ones (bc basically CR was the only one around) and the ones at the KHP and I felt I got a better course, judge footing etc. Plus I got to show with my friends so no FOMO. Now there are a few more options.
Good luck this weekend! I’ll be there too! I think you’ll love the starter course-Keeneland PCs jumps are so cute and ride well.
