When you say "slot is checked very rarely", does that mean that most checks ignore "slots" entirely and just look at a target's overall AC (or some other measure), or are you saying that the ring slot in particular gets checked very rarely (relative to other slots)?

Ah. I was thinking "light armor use" was based on weight, instead of material. Looking at all the armor use helpfiles as a group, it does make sense that they're all material-based.
