I use graphite in my sand but steel in my lob. But, I generally use my 58/60 LW from the bunkers.
I like the same feel for the sand wedge when I’m just playing it like a short(er) iron.
if it were primarily using it from sand, I’d probably go steel.
I had this realization about a month ago after 15 months of lessons on indoor launch monitor/simulator 😖
I was wondering why my shot dispersion in simulator lessons was so much better than on course. My instructor gave me a 5 minute lesson on alignment, that pretty much fixed the on course issue.
The lines on the hitting mats at my facility almost ensure you can't line up off target unless you try.
