It isn't the arrow it's the Indian.
I've played with all kinds of irons and except for not liking wide soles on firm turf or thin soles on grass like zoysia the rest is really a non factor.
I learned this as a kid caddying when I watched one of the adult caddies shoot one over using a set of baloney slicer hickory shafted irons and a at least 20 year old persimmon small headed driver which had a steel shaft. The driver was from the time when clubs were transitioning to steel but to make them look like hickory they had a coating on the shaft which made it look like wood.
I learned that day if you can play you can play and if you can't no amount of money spent on the latest design will make you a player. All that will happen is you will be a well equipped hacker.
