Played PX Blue 6.0 in my Titleist 910 Driver and Wood for about 3 months now in A1 (neutral) setting.
Always felt there was something wrong with the Driver.
Went to a clubmaker for a Spine Check and the result was horrible.
In the Digi Flex Machine the shaft moved like a Rollercoaster.
After Spining the Shaft there was a 40 degree turn to the right necessary to make the shaft work in the right way.
Plus a new adapter.....
Actually I am very disapointed how they just put this high qualtity shaft in without checking the spine (just the logo turned by 180 degrees)
As we tried different settings with the Hosel it became more worse. Only that one position of the shaft worked and showed good results.
Always thought PX are spineless Shafts.......
Compared it with a Matrix xcon and this one worked in all positions very well.?
Means to me for my next 913 driver.
buy it....pull the Shaft.....spine it... get a new adapter....put it back in place......do not use the Sure fit Hosel........???
