I am currently playing a set of Sub 70 699 with recoil graphite shafts since last Fall. I am a 3.5 index and would loved to do a comparison of the two models.
I have been an avid user of the Bridgestone B300-RX and the BRX for several years. Before that I played the e6.
I am 74 years old and post a 3.8 index. I live in Central Virginia and am a member of a private course.
Looking forward to the new Bridgestone balls next year.
