I'm looking at upgrading my old 585 19d hybrid fitted with a Stiff Aldila NV85 - i have a tendency to lose shots to the right, either straight block or fade.  It would seem the shaft is a little too stiff or could it be the torque?  I have the lighter shaft in an R7 driver and it's spot on for me?  Swing speed with the dirver is around 105mph on a launch monitor, and ball speed 145mph?

I've looked at changing it to the 910 19d with a Diamana Ahina 90 for Titleist shaft, but am i getting something similar to the NV?  Tested it briefly at the weekend and looked ok, although possibly less height than my existing club.  How would the Kai'li 80 shaft compare?    

Thanks,

Ed
