Ok, good to know! Guess it makes sense though the CE got the US version in 2016 and the 30th Dragon had them in 2015 but my 30th SE has HFS/VBs
My 2016 S2 Custom 24 had HFS/VB in it. I sent the serial number to PRS customer service and that’s what they sent back. I confirmed it when I swapped them out for some 57/08’s. I’m interested to see what a magnet swap does for them.
