I'm going to apologize before I get going here, because my intent is NOT to make anyone angry with my response, NOR am I being a wise-guy.
My first impression in reading this thread is, "What are you thinking?" In that, here's what I mean: What clubs (that you've paid $200, $300 even $500 for) did you get "fitted" for? How good is your swing right now or your current game?
Before I'd spend a nickle on any club, I would want to make sure it fits me, my swing and my game. I have been making my own clubs (i.e. Golfsmith, Golfworks) for years and wouldn't think of buying a club off the rack - if I didn't know it was good for my game/swing/style.
As an example: If you buy an off the rack Nike (say), it has what, a 45" shaft? 45.5" or even maybe 46" shaft? Is it stiff, x-stiff, regular, senior shaft? You can look but you can't tell. Is the Bend Point high, mid, low? What's the playing loft of the club in your hands (not the loft that's inscribed on the back)? In other words do you want the ball to go higher, lower? Do you - can you - work the ball or do you just want it to go straight?
What's the overall swingweight and MOI of this new club compared to your favorite "feel" club, like a 7-iron or 8-iron?
My point - again, not to anger or incite critisism of these posts - is, get fitted for a your clubs before you buy. Head to a Golf Galaxy or a place like that that fits clubs for swingweight, length, feel, overall weight, loft and lie AND especially your swing. Buying a 45.5" driver (because Tiger hits his 45.5") does you no good unless you can put the center of the head on the center of the ball, consistently. To do that - which is what golf is all about - you need a club that fits your game/style/feel.
I'm a big proponent for getting fitted for clubs before buying them Or for me, making them). Now that they run 2, 3, even 5 hundred bucks each, I wanna know before I buy.
Sorry for the very long, long post. I hope no one gets mad at my thoughts, here. Thanks!
