Getting fit for clubs is important. Proper length, weight, flex and lie angle are variables in club-fitting that can make a club set proper at impact and be more comfortable for the player to swing their best. Head style and intangibles may help the ball fly better and make the game more enjoyable. Be careful though that you don’t over-think it or believe that “fitting” can make the ball go straight every time. That is the player’s job to make a good swing. And just because you order “custom” clubs (i.e. different shafts, strong lofts, bigger grips, etc.) without doing a fitting doesn’t mean they actually fit.
