I’ve got my first judo competition next month and I’m planning to compete in the -81 kg division.

For reference, I’m 178 cm tall and currently around 84 kg, 22 years old.

I’d appreciate some advice on how far I should cut. Should I aim for something like 80 kg, or even 78 kg, or is that too aggressive? Is 4–5 weeks enough time to do this properly, or would it make more sense to just move up and compete in the -90 kg category?
