So.... to me it sounds like a fun match.
Because there's not a lot of opportunity to do these (done only monthly over here, may be more rare elsewhere), you want to cover your bases and target the level class you want to enter in. <= Long schpeel for, if you intend to title in BN and CD this spring/summer... I would absolutely focus on getting enough practice at the CD level which is more difficult than BN. Meaning, I'd also want to be practicing my stand stays, off leash, finishes, etc.
If you can only do 1 entry - I'd do a regular novice run + ask if you can do the walk around the ring after your run instead of the sit stay get your leash.
If you can do 2 entries - do both a BN run and a CD run.
Fun matches are or can be two different things....
If you have a dog that's literally READY to compete, is competing, etc.... fun matches are for practice + seeing what you need to work on. Especially right after a long break.
If you have a dog in training.... then fun matches are both for the experience/training + seeing where your dog is. Particularly watching what you are still doing to help your dog (additional commands, handling, etc).
***I did fun match on Sat and Jovi was a straight run through like I was in a trial. Because he is competing in open, etc.
Rather than waste an entry on novice with Glee - we did an open run with him as well. This was because my hope is to jump right into open after he's got his CD - but also the open run more or less works on everything we need for novice on a more difficult scale. Glee has 1 CD leg at this time.
So formal run with Jovi. Glee, I did more handling + motivation things because he's still cleaning up. IE, drop on recall, he comes flying like a freight train, so I do a more emphatic drop signal + verbal (you cannot do both in ring) and tossed the treat back behind him. Ideally, I want him anticipating drop a little more and watching for a signal or verbal command.
^^^ I did a lot of circulatory patterns with that explanation. LOL.
Basic answer is enter both if you can.
If you can't - enter regular novice.
Also - we pre-enter matches here. So there isn't waiting around. You show up close to your assigned times and go. Most early sign ups, the penalty is you have to volunteer judge/steward for a time slot in order to sign up for another. If you hold off until after all spots are filled, it's possible to just show/go without working (but very few spots at that point).
