Purchased a demo set of irons that had the N.S. Pro Modus 3 120 stiff shafts. These shafts are amazing. The only problem is the long irons are a little tough to hit consistently.. I decided to soft step the 3,4,5, irons with the Modus 95 regular shafts and bingo, what a difference. Added another 15 yards with each club and straight as a arrow. These are the best shafts I have ever played with.
