I think I know now the reason why 2 to 3 out of 10 shots with my 60y cleve falls short at least 15y when I aim at 45y for a 40y hole at st andrews first hole... And I get water.
Those shots felt like I was in 30-40% lie rough, when I was on the fairway. I love those wedges, except in those situations that felt wtf...
I play st andrews a lot to lower my average. And hole 1 really feels like there's no trick to it.
Those cleves allow me to get lots of under 3y approaches, regardless of wind as I feel the adjusments I make work.
So when with no wind, that glitch started to appear, it really felt strange. I'm now very sorry to understand where it seems to come from.
