I was recently fitted to a 9.5 deg 910D3 (UST Proforce V2 76) at B4 setting.  This was due to a big in to out swing & steeper angle of attack I was making whilst being fitted.  A direct result I think of the time spent trying to groove that into my iron play.  I anticipate moving back towards A1 when I put some work into my driver.  I believe that if/when I adjust the setting from B4 the shaft rotates?  I'm not sure I understand how this is, isn't the lie/loft  change actually made to the head of the club?  Has anyone made big adjustments with their driver & does the rotation of the shaft become an unwanted distraction?
