With the X series, Donnay made it easy to distinguish the differences in the 1,000 or so variations they produced, however I can't tell exactly where the x series is different from the Xdual series (aside from the marketing). What are the major differences between the X-Blue and XDual-Platinum in the 94" head size? Is the XDual-Platinum from the same mold as the X-Blue? Does it have the same head shape and drill pattern? If not, what are the differences? How much different is the feel of the rackets? The Blue feels somewhat like a cross between the prestige and prostaff. Where does the platinum fit in relative to the blue?
