I think you make a good point there, why would companies offer custom fitting for free at heir own expense to help you use their equipment better if it was pointless. Why does every tour pro get fitted for their clubs? Go on a YouTube channel called TXG and maybe you could learn a thing or 2 about custom fitting. There is a good one on there where an older every day golfer gets fitted for a driver and the difference the shafts make. Or go on Mike Newton Golf and watch him doing shaft comparissons. Or any of a thousand YouTube videos with people getting fitted and the difference it makes.
But being a child and saying about cutlery is a little bit of a stupid arguement don't you think. But hey go troll someone else cause I really could not give 2 ............. about what someone like you has to say if they can not even form a sensible arguement.
There are certainly gains to be made, but unless you're physically very much different to the average, how great are those gains?
What sort of difference will it make to your score?
Several shots a round?
A shot a round?
A shot over four rounds?
This is where the grey area is and nobody seems able to give an answer. Unless you're clubs are hopelessly unsuited to you, IMHO the gains won't make much, if any, impact on your score.
In any case, it's not all about the score.
