I'm presently using 710 AP1 irons with the Aldila  75A graphite shaft. I want to upgrade to the 714 AP1 irons but need some advice on what graphite shaft would be comparable to what I am presently using. I am a senior with a moderate swing speed. There are so many shafts to choose from that I find it difficult to find the same shaft and weight that will provide the same swing and loft capabilities.
