Fun fact: my golf bag was 1 pound lighter for my return trip then it was on the way there. It was 50.5 pounds on the way there, .5 pounds below overweight, and 49.5 on the way back. I blame the rinsed sleeve of balls and the snacks I ate during the rounds.
Against my better judgement...
iacas is a pro who hits the exact sweet spot about 3 times in a round - 8% of about 36 full swings over 18 holes. However, I’d guess he has way, way more solid strikes that feel almost butter soft in a round.
Clearly I should have said “solid strikes” in the OP instead of “sweet spot” or even “center” even though many golf media/publications (mis)use the terms somewhat interchangeably.
