club choice, advice needed

Hi Guys and Ladies,

I have been playing for just over 12 months, joined a local course in April, and have had one or two rounds well below my 28 club handicap. I have been using Ping G2 irons but last week went out with a set of Wilson Fat Shaft Tour Cast and my game seemed to improve quite a bit.

So should i go and get the Ping custom fitted or ditch them for the Fat Shaft with a view to return to tem when my game is a lot better.

Your advice would be appreciated

Thanks 

I take that as your implying the Ping G2 are counterfeit?

They were purchased from a local Golf Pro Shop and have been registered with Ping by my father, the previous owner. Could the fact the clubs were custom fitted to his swing be a major factor?

I myself dont feel i have a consistent enough swing to get them adjusted to my needs. As a high handicapper would having them adjusted now benefit me more?
