Chris, you've got a lot of good things going on in your flying, and you are open to trimming advice and getting good advice here. All I can add, and I think you know it, is there's more to Beginner than just the flight. It's about getting your routine figured out. That means metering your fuel and getting the plane placed where you want to take off, not just where everybody else does. And if you're not comfortable where the judges are with respect to the wind, asking them to Please move to where you think they'll be opposite your stunts. Then priming, signaling the judges, getting cranked and running like you want it. After that, it's all flying. That's what Beginner is all about, and it's still cool to bring home a trophy, there's no asterisk saying "He didn't have anyone to beat." And your Mom and friends will think you're an expert Lol. Well, at least mine does.
And once you've done it once, for the rest of your life you can always say, "I flew competitive Control Line Aerobatics." And nobody can take that away.
Good luck, and have fun.
Rusty
