What do you think the odds are that so many tour players who, as earlier stated, play cavity back/game improvement-type clubs do so because of sponsorship. I would assume that these are the style of club most marketable to the ever-growing population of new golf enthusiasts and that OEM's might 'sweeten the pot' for tour players to use these over what they might actually prefer.
Back to the topic at hand...I play an old ('79) set of Wilson forged muscle backs and I will take them with me when I leave this world. Have played Eye2's and Titleist 962b's in the past. I liked both these sets, but now cannot stand to look at anything offset and large. To me, lots of these new clubs belong in a gardener's tool shed.
Because of reasons listed above, I have not tried going back to cavity-back irons. However, I do know that in the time I have played my 'blades', my game has improved immensely. Reason? I think it is the fact that blades reveal more symptoms of my less-than-perfect swing. This has pushed me to be more of a student of the game, to work harder and more productively to improve.
Conclusion: The clubs you play should depend on long term goals. If you are just looking for what will help you improve NOW, cavity backs probably are the ticket. For long-term improvement from a committed golfer, go with the blades.
Sorry for the length of this, but it will probably fall on deaf eyes because the thread is a bit old. Just wanted a little rant in my first post on the A1 golf forum.
