I started with a Hagen international set, 1,2,4w and 3-pw. I have played Ping, Adams, Callaway, Nike. The ones I played with the longest was Adams irons 3,4,5 hybrid 6-pw with a Cleveland DST driver. The rest is like a blur.
Power built is a good starter set, I have the STi 2 iron set 6 thru gw. I would say the STi 2 is a set you would keep for a long time, and you came add any irons you want. Maltby is a great set that plays well.
I have changed my irons and went from fw to hybrids. Now I amd changing the shaft in my driver, ordered a shaft adapter and regular flex shaft form golf works. Will post pictures when I get them.
