The main difference, or should we say advantage, of buying clubs individually is that you have a lot more freedom. There are lots of professionals out there who don't have equipment contracts because they want to be able to chop and change as they wish, and use different clubs they like the looks, performance and feel of. At the other end of the golfing spectrum, buying a set is ideal for beginners because it often saves a lot of time and money because all it requires is one purchase which can be very inexpensive as well.
