I have a 4 wood and a 5 hybrid with the Tensei Blue.  I purchased a 21 degree HyWay with a Maltby Pro Fairway.  Both Regular flex.  I fine playing the Tensei in the fairway and hybrid.  Very pleased.  For the life of me, I’m struggling mightily with the HyWay, nothing but hard fades and slices.  So, I’m looking for an excuse.  How do these two shafts compare outside of weight?  Thank you.
