Progress Golf BB6 HI COR Driver Head
Head will need to be shafted. Please contact us for shaft options
Other shaft options are available. All BB6s are to be shafted and no head sales.
Our new AutoFlex SF505 is 51 gram, SF505X is 54 gram.
If you are a swinger who swings smoothly, SF505 will be good.
If you swing aggressively and fast, SF505X will be better.
X doesn’t mean the Flex as the other shaft brands.
Our X means, this holds better with the faster swing.
