Mizuno Fli-Hi II Hybrid Shaft Replacement: Expert Advice

Question
I have a Mizuno Fli Hi II Hybrid 18* head that needs a shaft.  I have the Fli Hi II Hybrid 21* and 24* with Exsar Fli Hi Graphite Black shafts (Regular flex).  I am considering reshafting with the Graffaloy Lite Attack shaft but would like your thoughts on this.  I have not found the specs on the Exsar shafts yet.  What would you suggest as a suitable replacement.  Thank you.

Answer
Hey Norman,

Sorry for the delay in getting back to you. I'm writing to let you know that unfortunately I don't have much information for you. I returned to competitive golf a few months ago after 12 years away from the game. I just don't have the technical knowledge to help you with this question. I'd get in touch with someone at a golf store or pro shop who routinely deels with reshafting questions.

Thanks and good luck.

John
