I have an older Cobra with Icon FH shafts that I built several years ago. Sold it to a guy and regretted it about 2 weeks later. Last summer I was able to get it back. It's in my reserve bag right now but I have it on standby.
Last year I got my dad a Callaway XR 4 wood. He hits it extremely well... better than any 3 wood. He told me last Friday it was the best club in his bag. He likes it so much, he is seriously contemplating adding the 9 and 11 woods. He is 71 and has trouble hitting any iron over a 7. I think he will have all woods and start his irons at the 8 before the end of May.
