Let me put my thoughts in this, dohoho.

I understand why you don't want mirror and agreeably it does make some charts easier when you flip the entire song, HOWEVER it's not changing how the step artist intended it to flow.

This is why mirror records and why other mods in R^3, like scramble and random, do not. It's because those mods change the entire flow and breaks both what the step artist saw AND the flow that the step artist made.

However, this is your tournament and don't mind the lock on the mirror mod, it would make some charts trickier to nail (depending on what hand you're strong in). Just know this is why mirror records.
