Actually, the only logical explanation for the Raptures being the most expensive is from a strictly economic point of view. They are the only "premium" set of clubs available to Hacks and above, so I guess the rationale is charge the most for them, knowing that a great # of people will buy them in the beginning for rapid advancement. It's kind of the 'deal you can't refuse' if you want some extra oomph in your game right from the start.
Like I said above, I don't mind paying less for the best clubs. Were we to base price on performance, however, they would be half the price they are now. Anyone who argues that they are rightfully the most expensive are using justifications that make no sense. It's akin to saying, "Well, my Toyota Camry stays on the road easier, drives at a more manageable speed, and gets better fuel economy than your Maserati, so it should
be more expensive" Guess what? In the hands of the right driver, my Maserati is going to leave your Camry in the dust over and over. Camrys cost $20,000 USD, Maseratis cost over $100,000 USD.
