Currently have Apex CF16 irons with KBS Tour 90 stiff steel shafts and hit them very well.  Am thinking of getting Apex CF16/Pro combo irons with Project X Flighted 95 Steel 5.5 shafts.  Would appreciate comments from anyone who has experience with both KBS Tour 90 stiff steel and Project X Flighted 95 Steel 5.5 shafts.

 

Thanks!
