Hi everyone. I am in the process of working on my KB helmet, cleaning out some of the debris from the cast in the tube stripe slots, and I am wondering what the rule is on actually cutting out the slots straight through. The wording on the CRL is 'cut out', but I am not sure if it's cut out completely or just recessed. I have seen at least one build thread on here that looks to have been cut out completely, but most of the references images seem to look like it isn't cut all the way through or it's inconclusive.
