Yes, I mean favorite, it's my absolute favorite, and I love it. Plus, I came up with it, so yeah. Depending on what my limitations are with Max, I'd like to be able to take him through this. I'm totally sending it to Coach S because it might also work for IEA/IHSA courses if not just as something to practice with. So, onto the diagram.
It's a five jump set up (square oxer, airy vertical, large X, & the line) with plenty of room for variation. All fences are set to be jumped from either direction. The line is set for a moving 3 or conservative 4, meaning that you have to think and, ya know, actually ride through the thing instead of sitting there doing nothing like some people. One of the nice changes you can make to this is lengthening that line so that you're able to do a bending line between one of the line fences and either the oxer or cross rail (extra diagram below). You can decide which distances should be unrelated or measured.
