I measured the lofts on a loft/lie gauge at each score line on a KE4 ST-2 10.5* driver and the STw 10.5* driver. I understand that each driver has vertical roll and the loft measurement will differ depending upon the area of the face the measurement was taken. On both drivers I measured a 1* loft difference from score line to score line. Is this by design, a coincidence or do I need to take more careful measurements? If by design, is this consistent with all Maltby drivers? Thank you in advance for the response.
