Big difference in the standard vs Pure X shafts, one is LD, other is not. Although the Players Pure X (HXT) shafts are not as LD as most others, especially the larger diameter one. As far as the butt is, both are same build and pin.
Someone I knew got one and sold it as SBE for more than what he paid for it used.
