I think it is the other way around. People playing "what they think they should" rather than playing what they should. But I am not here to critique. If it makes someone happy to play what they play then all the power to them. I will use an example. Only an example. You list in your signature that you play the Pro V1 and ProV1x. Both very good balls. But both of those balls are for VERY different swings and very different players. Changing a ball like that will produce drastic differences. Now if you said I play the Pro V1 Srixon Z star Tp Black Nike One Tour etc... Those are all similar balls. Again I am not judging and I am sure it works for you, especially as someone that puts in the time to better himself on the course like you do. But we see this all the time. I have had the opportunity to play with over 20 of the members of this site. In that time NOT ONE person out of the group had been fitted for their irons. Not one person had been fitted for a shaft, and NOT ONE person had been fitted for a ball. So that opens up another question. Is it all about marketing? It has to be right?
