Re: who needs 14 clubs anyway??
I don't know how long you've been playing, but the odds are that you didn't use that club when you were a 20 handicapper. If you did you probably sucked with it. Not trying to pick a fight but that's just how it is. The radical face angle makes a much smaller effective sweet spot than even a 56°. And it gets worse with a 64°. A typical 20 handicapper just doesn't have a swing that can hit that sweet spot consistently.
Anyone with a decent swing can probably learn to use one with a lot of practice dedicated to that club, but I personally would rather devote my time to practicing a couple of more versatile and forgiving clubs (my 52° and 56°). I can pretty much do anything with them that I could with the LW, and more. And on that one time in 3 or 4 rounds where I'm in a position where the LW might be effective, I play the best shot I can with what I carry. I'm not going to spend the little bit of practice time I have available on a club that is of such limited value to me.
By the way, I have a 58° and 60°.... both live full time in the spare bag in my garage. They are better for my game there than on the course with me.
