DON'T LISTEN TO ANYONE HERE! LOL
You are only going to become more confused. There is a conspiracy in the industry and it is well permeated in this forum. They want you to buy two sets of clubs, possibly three. One to learn to hit the ball with, one set to learn to make the ball go and then one set to make the ball go where you want. If your going to get a set, get a set you feel like a million dollars in. All the clubs are designed to go the same distance, by rules of the game of golf. I'm you don't think Tiger is above putting Titanium in his putter head to get an advantage then your wrong, The thing that stops him is the rules. Golf clubs are like a pair of boxing gloves or a pair of running shoes. You will do all the work, the equipment just sort of gets in the way. Go with a club that is EASY to HIT and EASY to CONTROL. Whatever equipment you think will make that happen, then go for it.
I have a thread about Mizuno with several emails from Mizuno actual regarding when a player is "ready" for a certain club. Between them, the "pro's" at the store and the infinite wisdom of the Internets I find there is a huge lack of consistency regarding equipment. In the end I think the choice of equipment is a personal matter that you are best left in control of. I'm not even sure fittings are all that helpful. It's a relatively new tech and how anyone one the Masters prior to 2000 is beyond me.
