Steel to Graphite shafts

[chessbum]

I am 59 and an 18 'capper. I play almost everyday, except 2-3 months during the winter when it's very cold and snow on the ground.

I have a set of Titleist OS 804 irons, steel shafts. I am happy with them. I have been thinking of re-shafting them with graphite along with a custom fitting.

What is your opinion on moving from steel shafts to graphite??
