The BJ-3 was a typo, it was right in my spreadsheet. I also fixed the Trebuchet cost, as I was contemplating adding other stuff to it, and never undid the extra costs. The only issue with that CN9-D variant is close to 10 mil in C-bills in megamek. I am now on the fence for the clan weapons, and now want some clan mechs to use that better tech. Other than the Centurion, is anything else an issue?
