I mean base frame before any customization? Similar like all Head Pro Stock frames are ? Same and light ( 305g unstr. like biciomac said) or same and heavy (330-340g unstr. without any lead like dr325i and jsomrak are saying) ? Or maybe they are 305g and then customized with silicone in the head to 330-340g? Or are they totally custom frames and every one is different and custom made for some pro, with different layup and weight from the factory?
