I only own 14 clubs...and I don't think I'm good enough to benefit from changing them out. I would guess that the only justifiable change for a golfer at my level MIGHT be a switch from a hybrid to an iron in really windy weather...but I only have a 3-hybrid and there's no way I'm hitting a 3-iron.
My setup remains the same regardless of where I play. So does all the junk in my bag - I just looked through my bag yesterday and found a Poipu Bay Golf Course scorecard still in my bag. I played there in 2016, so I guess I have not gone thru the bag since then!
I can't tell if he is trying to say something similar to what Adam Young talks about (impact over everything, which I personally like) or if he is going the Jim Ventos route. I'm getting weird vibes from this one though.
