As with Titleist, there are several series of TA clubs that are geared to various levels of ability. If you want to go to the next level, then find a local pro shop with a fitter you can work with. Titleist doesn't sell a boxed full set, so that person can help you improve irons or driver or whichever clubs don't match well with you. With the line of clubs that works for you. For example, there are 10 lines of irons. Only your fitter can recommend a club for you. If you see the difference at the fitting, then buy it.

If you went to a Team Titleist event with 72 of us crazy followers, you won't find 2 bags that have the same combinations of clubs. Because no one "boxed set" is the right mix of clubs for any one golfer.
