In addition it gets 100% of clubhead separation velo, which is at best 80% of impact velo due to energy losses. So assuming the best case, this gives a separation velo of 80 mph. So ball speed is 70 + 80 = 150 mph. Thanks indeed, now I understand. Weightshift View Public Profile Send a private message to Weightshift Find all posts by Weightshift
