Forgive my stupidity, but if they use the same cases is the pattern moulded from a different material or do they just "dip" a steel case?Nope. It looks like VSF is using the same case. I have a newer VSF and the crown guards are better than the older ones (I compared it to my old ZF and VSF actually looked slightly bigger!). But the new maroon bronze/green and the black and metal on mesh have significantly bigger CGs than the regular SMP300s. VSF needs to make a new case.
