True. Then again all you have to do is look at the most used brands on the professional level to see what equipment is the best. Professional golf is such a cut throat business for these guys and for the vast majority they make their living based on how the finish in tournaments not on their endorsements. Most people wouldn't have a clue just how hard it is for players to make it to the PGA Tour level and how hard it is for them to stay there. Thus they are going to use the best equipment available to them to stay there and perform at the highest level.
That isn't the be all end all of what clubs are best for the average golfer but it does give you a pretty solid idea as to what clubs are the best performing clubs you can buy.
So you do not buy the best deal at Costco? Now seriously, outside of Tiger, what drivers they use. The pros also have a very fast swing to match.
