Hi Plainfaced, the set in your kit is 10-46, Regular Slinky. As a rule, we generally include 9-46 with all solid body kits and 10-46 with hollow body kits. Sometimes we might be out of one or the other, so we include what we have.
I've not heard of 11-46, but I'm sure someone does them, somewhere.
Edit: D'oh. I just tool a look at your photo again and, yes, they are a Custom Gauge, 11-46.
I'm assuming this is just a happy mistake.
I will ask my CMC contact if we can get a few sets of these for you.
