Shaft to put in 910h

Currently I have the Mitsubish Rayon Diamana 'Ahina 90 in the club now and it is way to heavy. It feels as if I am swingging a two by four, zero flex. What are your guys' thoughts on replacement shafts? How is the Kai'li 80? Any ideas would be great. 

Thanks!

Philip, 

Any of our custom shafts can be ordered individually.  The Kai'li 80 will certainly play and feel softer, but keep in mind how it will change your ball flight (slightly higher and more spin).
