I was a club shorter but had the Microtaper shafts...might have made a difference. My spin though was just too much combined with the fact that after 30 years of use God knows what the lofts and lies are now. About the red dot/black dot.... I wouldn't pay too much attention since the clubs are 30 years old, probably been hit off of mats... God knows what the lie angle actually is now.
I was playing green dots which would be 4 off of my static measurement. Right now I'm at standard and get the same marks on the lie board as my old becu green dots. Gotta figure they say to have your lofts and lies checked every few years...its been 30.
