Fittings will refine your swing needs as a low handicap golfer but as a high handicap golfer, you might be missing out on some basics from a fitting. Physical stature might require longer or shorter clubs or flatter or upright lie settings. They can also get you in a shaft that closely matches your swing speed which may change over time but will probably serve you well through your early progression. Fittings are always a good idea, especially with Titleist applying fees directly to your purchase and final club costs being no different than off the shelf club cost. I say, go for it.
