OK, got a reply back from Yamato regarding the running changes to the 1/60 V2 shoulders starting from the DYRL Max VF-1S type and the only thing that has been changed is that the knurling has been removed from the ends of the shoulder pins.
I was hoping as I'd discussed with Yamato and the Chinese factory owner a few months ago, that the pin diameter would be made smaller, thus allowing the plastic around the pin to be made thicker.
Hopefully, removal of the knurling will lessen pressure on the plastic and eliminate the cracking issue, but I guess we'll just have to wait and see.
Honestly, I was hoping for more, but hopefully Yamato and the factory have done their homework and this change is all that is required.
