I currently have cobra one length (9,8,7,6,P,G,S) irons and 3,4,5 hybrids, all R flex; and need to go to a senior flex because of age. I’m thinking of getting 10 uncut graphite shafts, making the (9,8,7,6,P,G,S) at the 7 iron length and the hybrids at the 4 hybrid length. How do I trim the shafts to maintain the senior flex?
Thank you for your reply
